The L-Dens 2300 density sensors – flexible, compact OEM modules – deliver 3-digit accuracy especially at low flow rates (≤80 L/h) and can be easily integrated into different instruments and systems. That’s why L-Dens 2300 is the cost-effective solution for integrated density measurement.

L-Dens 3300 is a flexible, stand-alone sensor for inline density measurement and concentration determination at 3-digit accuracy. A wide range of application options makes the instrument extremely versatile, even for small lab production setups in various industries. Wetted material available in stainless steel and borosilicate glass enables the measurement of both non-corrosive and aggressive media such as sulfuric acid.

Key features

3-digit accuracy, especially at low flow rates (<80 L/h)

3-digit accuracy, especially at low flow rates (<80 L/h)

The compact L-Dens 2300 OEM module and the stand-alone L-Dens 3300 sensor deliver 3-digit accuracy for process liquid density and concentration measurements, especially under low flow conditions (<80 L/h).

Easy installation: A fit for tight spaces, resistant to aggressive media

Easy installation: A fit for tight spaces, resistant to aggressive media

No space? No problem. With the L-Dens 2300 OEM module, the sensor and process board form a small, compact unit easily integrated into different systems – which can therefore be designed to be more space-flexible.

The all-in-one, multi-application L-Dens 3300 sensors are versatile across industries (e.g., petroleum, chemicals, and beverages, as well as for public research institutions). The sensor is ideally suited to, for example, lab reactors and pilot or production plants. These sensors can be ordered with or without HMI.

The wetted parts are available in stainless steel for standard applications (non-corrosive liquids) or in borosilicate glass to withstand aggressive process liquids. Choose the material based on your production media.

Zero maintenance, zero consumables

Zero maintenance, zero consumables

Once L-Dens 2300 is installed in your system or the L-Dens 3300 all-in-one solution is set up, no maintenance or consumables are required – keeping operational and capital expenditure down. 

Large application database, customized formula development
