Connect to your handcrafted beverage!

  • EasyDens determines your wort's extract content, the sugar content in your home-produced fruit juices and the alcohol content in spirits with no sugar added
  • Monitors the fermentation process of beer and wine via a daily measurement of apparent extract or sugar and visualizes the process in a fermentation chart
  • Provides homebrewers the information you need to decide when it's time for bottling
  • After downloading the free app for EasyDens, your results are displayed and stored on your smartphone, ready for export to a PC
  • Simple, quick and reliable measurement using only 2 mL of sample

Key features

EasyDens is true to its name

  • Reports give the measured results for density, SG (relative density) and one concentration unit of your choice (extract in % w/w, alcohol in % v/v or sugar content in °Brix)
  • The two other concentration units are available via in-app purchase at any time
  • Concentration values are already temperature-corrected, so you need no further calculations or correction tables
  • Covers the entire measuring range needed for production of your homemade product
  • Measurements are done in less than a minute, including filling and cleaning
  • App for download on smartphones with operating system Android 4.4 - 9.0 or iOS 13.0 and higher.
  • Data exchange between EasyDens and your Smartphone via Bluetooth Low Energy

Keep your homemade product under control

  • EasyDens helps you to ensure that your homemade product ends up the way you intended
  • It monitors the fermentation of your handcrafted beverage and visualizes the process in a fermentation chart
  • Measurement data can be saved and exported from the EasyDens app to further process them on your computer
  • For homebrewers: the alcohol content is calculated from the measured extract/specific gravity results and is shown in the automatically created chart
  • Enhance your production skills by learning about the influences of your raw materials and production process on the measured results
  • Get the maximum drinkable volume – only a small amount of sample is needed for testing

Straightforward measuring procedure

  • Samples containing CO2 and big particles need to be filtered before filling the measuring cell
  • A few milliliters of sample are filled into the measuring cell by syringe
  • The measured results are displayed on your smartphone moments later

Robust and maintenance-free design

  • Robust design ensures a long-term working relationship
  • Clean, calibrate and re-adjust EasyDens yourself, with some deionized water
  • EasyDens is based on the renowned oscillating U-tube principle, which is also applied in the world's most accurate density meter, DMA 5000 M.
