The portable density meter EasyDens measures the density of liquids by the oscillating U-tube method. In addition, a temperature sensor measures the sample temperature directly at the measuring cell.
You operate and control the instrument via the "EasyDens" app running on your smartphone. For the communication between EasyDens and your smartphone, Bluetooth is used.
EasyDens features various measuring units for display:
The density (ρ) of a sample is defined as its mass (m) divided by its volume (V):
| ρ = | m/V |
As the volume changes with temperature, density is a temperature-dependent quantity.
The sample is filled into a U-shaped borosilicate glass tube that is being electronically excited to vibrate at its characteristic frequency. The characteristic frequency changes depending on the density of the sample. With the determination of the characteristic frequency, the density of the sample can be calculated. Due to the temperature dependency of the density value, the temperature of the sample has to be determined precisely.
In binary mixtures, the density of the mixture is a function of its composition. Thus, with the aid of density/concentration tables, the density value of a binary mixture can be used to calculate its composition.
This procedure is also applicable for so-called quasi-binary mixtures. These mixtures contain two major components and some additional ones in very small concentrations compared to the two main components.
Many decarbonated soft drinks, for example, can be considered to be quasi-binary mixtures of sugar and water because the concentrations of flavors and acids are very small compared to those of sugar and water. Hence the sugar concentration can be determined with a density meter.
The same holds for the determination of the alcohol concentration in distillates that can be considered to be quasi-binary mixtures of ethanol and water.
EasyDens has been tested and packed carefully before shipment. However, damage may occur during transport.
Keep the packaging material for possible returns and for further questions from the transport or insurance company.
To check the delivery for completeness, compare the supplied parts to those listed in table "Supplied parts".

Handling samples with temperatures of more than 50 °C (122 °F) bears the risk of burns.
Wear appropriate protective clothing or take other protective measures when you handle hot samples.
Observe the maximum sample temperature. At temperatures over 80 °C (176 °F), plastic parts soften and connections become leaky.
Before you perform a measurement, make sure that the wetted parts are resistant to the sample and cleaning agents, see appendix "Wetted Parts".
Sample containing dissolved CO2 will cause bubbles in the measuring cell which will lead to invalid measurement results. Degas your sample carefully before measurement.
Either
boil the sample for several minutes,
or stir the sample for 5 to 15 minutes until no more bubbling occurs,
or put the sample in an ultrasonic bath for approx. 5 to 10 minutes.
Do not degas your sample by boiling or stirring it in an open container if it contains volatile components which you are going to measure, e.g. alcohol. With these methods, the volatile components will have (partially) evaporated after the procedure.
A suitable method for samples containing alcohol:
Fill the sample into a 1 L flask up to max. 1/3.
Seal the flask with a stopper.
Alternately shake the flask and release the pressure until no pressure is built up anymore.
Ensure that the measuring cell is filled free of gas bubbles. Reasons for gas bubbles in the measuring cell may be
gas bubbles in the sample,
leaky fitting of the injection adapters.
Fill the measuring cell completely.
Ensure that the sample temperature does not deviate too much (±5 °C/±9 °F) from the ambient temperature.
If the sample temperature is more than 5 °C/9 °F above ambient temperature, let the sample cool down before filling. You can speed up cooling with, e.g., a cold water bath.
If the sample temperature is more than 5 °C/9 °F below ambient temperature, wait before filling until the sample has reached ambient temperature. Do not use an auxiliary hot plate because alcohol might evaporate, and thereby the density of your sample may change.
Filling a very cold sample in a humid environment may cause water condensing on the U‑tube.
Carefully clean the instrument after each measurement series to avoid deposits in the measuring cell.
Have suitable solvents for cleaning at hand.

Specific Gravity SG or
Sugar content [°Brix]
as the measuring unit.
Save the measuring result and associate it with the sample ID for your fermenting product (see section "Saving a Measuring Result").
Simply access the data associated with the sample ID (see section "Accessing Data of a Data Series").
You will see a list of measuring results and a graph showing the decrease of your sample's extract content or sugar content over time.
The calculation of the alcohol content is a special feature for beer brewers only.
The alcohol content in beer is calculated according to the formula in the book by Hubert Hanghofer: Gutes Bier selbst brauen, BLV 2008 (ISBN 978-3-8354-0413-7).
In order to be able to calculate the alcohol content during or after fermentation, you need to:
select the application type "Beer" when you create the sample ID for your beer sample (see section "Creating a New Sample ID");
select Extract content [% w/w] or Specific Gravity SG as the measuring unit;
record a fermentation curve of your beer sample (see section "Recording a Fermentation Curve").
Access the data associated with the sample ID (see section "Accessing Data of a Data Series").
You will see the question "Want to calculate alcohol?" above the list of measuring results (see fig. "Turning on calculation of alcohol content").
If you do not see the question:
Select "Turn on alcohol calculation" in the drop-down menu.
Tap <Yes> to calculate the alcohol content.
Select the measurement in the data series marking the start of fermentation (original extract):
Tap <Tap here> (see fig. "Setting the start of fermentation").
Activate the checkbox at the measurement marking the start of fermentation.
Tap <Done>.
Confirm the setting.
The alcohol content will be calculated for all measurements beginning with the set start of fermentation. The values are shown in the graph of the fermentation curve (see fig. "Fermentation curve with calculated alcohol content").
Read the calculated values from the scale of the graph. Zoom in to see details.
Always clean the measuring cell after work at the end of the day.
You may need to clean it more often …
when you are going to measure a sample that could chemically react with the previous sample,
when you are going to measure a sample that is not miscible with the previous sample.
A suitable cleaning liquid must dissolve and remove sample residues in the measuring cell. It has to be a good solvent for all sample components.
Use warm ultra-pure (bi-distilled or deionized) water as the cleaning liquid for beer or wine samples.
Do not use tap water instead of ultra-pure water because tap water will leave limescale in the measuring cell causing the measurement quality to deteriorate.
Fill air with a syringe into the measuring cell to empty the cell.
Rinse the measuring cell with a suitable cleaning liquid, e.g. ultra-pure (bi-distilled or deionized) water.
If you have not used ultra-pure water as the cleaning liquid in step 2, rinse the measuring cell with at least 10 mL ultra-pure water to remove the other cleaning liquid.
Empty the measuring cell as in step 1.
Once a week, clean the measuring cell with a suitable laboratory cleaner (e.g. Mucasol®).
Be sure to attend to the product information concerning the cleaning agent's concentration. E.g., Mucasol® is to be used as a 3 % solution, Alconox® and Tergazyme® as a 1 % solution.
Do not let the laboratory cleaner soak in for more than 5 minutes because the glass in the measuring cell is susceptible to attack by alkaline liquids.
Fill the measuring cell with the laboratory cleaner and leave the cleaner in the cell for approx. 5 minutes.
Rinse the measuring cell with at least 80 mL ultra-pure (bi-distilled or deionized) water.
Fill air with a syringe into the measuring cell to empty the cell.
Dispose of the samples and cleaning agents according to legal regulations.
Clean the housing and the inspection window with a soft cloth dipped in ethanol or warm water. If necessary, you can use a mild solvent (pH < 10).
Before you store away the instrument, clean it as described in section "Regular Cleaning of the Measuring Cell".
After cleaning the measuring cell with ultra-pure water, empty the measuring cell.
You need not worry about the measuring cell being still wet as long as you take care that the instrument is not exposed to freezing temperatures.
Do not expose the instrument to temperatures below 0 °C (32 °F) when the measuring cell contains water. Freezing water will cause rupture of the measuring cell.
Store the instrument in a dry place at room temperature. Storage in an environment with high air humidity can cause damage to your EasyDens.
If the measuring cell is not sufficiently cleaned, residues can form deposits in the measuring cell. Over time this will result in your measuring values deviating from the correct values.
You can detect the effect by comparing the density values that your instrument gives for deionized water with the correct values (at the respective temperature) that you can find in appendix "Density of Water". The two values must not differ by more than ±0.005 g/cm3.
Conveniently, there is a simpler method:
The measuring unit "Specific Gravity SG" already comes with temperature compensation, so you do not need to consider the measuring temperature. And with this measuring unit, the target value for deionized water is 1, so you need not bother looking values up in a table. Tolerances are ±0.005.
The same holds for the measuring unit "Extract [% w/w]" only that the target value for deionized water is 0 and tolerances are ±0.3 % w/w.
Perform a check measurement with deionized water regularly, see section "Check Measurement".
If you get a measuring value that deviates from the target value by more than given tolerances, you need to readjust the instrument by performing a water adjustment, see section "Water Adjustment".
Clean the measuring cell as described in section "Regular Cleaning of the Measuring Cell".
Rinse the measuring cell thoroughly with deionized water so that potential residues from other cleaning liquids are removed.
Preferably select the measuring unit "Specific Gravity SG" or "Extract [% w/w]" (if available), see section "Selecting and Unlocking the Measuring Unit".
Perform a measurement (see section "Filling Sample and Measuring") with deionized water.
Read the measuring value.
If the measuring value is in the valid range for the measuring unit (see table "Validity of the check measurement"), your EasyDens is ready for measurements.
If the measuring value is outside the valid range for the measuring unit (see table "Validity of the check measurement"), perform a water adjustment, see section "Water Adjustment".
| Measuring unit | Target value | Tolerances | Valid range |
|---|---|---|---|
| Specific Gravity SG | 1 | ±0.005 | [0.995 … 1.005] |
| Extract [% w/w] | 0 % w/w | ±0.3 % w/w | [−0.3 … +0.3] % w/w |
| Density | ρwater (T) (density of water at measured temperature T) see appendix "Density of Water" | ±0.005 g/cm3 | [ρwater (T)−0.005 … ρwater (T)+0.005] g/cm3 |
Fill the measuring cell with deionized water.
On the menu screen of the EasyDens app, select "Adjustment" to start the adjustment procedure.
Wait until the readjustment of your EasyDens is finished.
For proper battery handling, also observe section "Battery Handling" of the safety instructions.
You find the battery status of the instrument on the measuring screen of the EasyDens app (in the bottom right corner, see section "The Measuring Screen").
When the batteries are depleted, the instrument switches itself off.
Slide open the cover of the battery compartment on the rear of the instrument, see fig. "Rear view of the instrument".
Remove the depleted batteries with the aid of the battery tape.
Insert the new batteries.
Ensure that the battery tape protrudes from under the batteries.
Consider the polarity of the batteries when you insert them in the battery compartment.
Insert only equally charged batteries of the same type.
Close the cover of the battery compartment.

| Extract content [% w/w] | To determine the extract content of wort and the apparent extract of beer; temperature compensated to 20 °C |
| Specific Gravity SG | For the calculation of the specific gravity, the density of the sample, temperature compensated to 20 °C, is divided by the density of water at 20 °C. A temperature coefficient of 0.0003 g/cm3/K is applied for the temperature compensation of the sample's measured density. This coefficient is typical for aqueous solutions. |
| Sugar content [°Brix] | To determine the sugar content of binary water/sugar solutions as well as "quasi-binary solutions" (e.g. non-alcoholic beverages); temperature compensated to 20 °C; see also section "Measuring Principle" |

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’etablissement d’une communication satisfaisante.
