Waterlab is the most technically advanced water activity meter, an essential tool for quality control of products and ingredients in the food, pharmaceutical and cosmetic industries. It is used wherever it is necessary to test the shelf life of products to determine the risk of microbial growth.


With a dew point sensor that measures actual water activity instead of secondary parameters, Waterlab is the most efficient device of its kind available on the market.


New calibration and control modes allow the user to optimize even for multiple analyses of samples with very similar water activity values. With the introduction of innovative computational and temperature control systems, Waterlab allows for a wide variety of tests: from simple control measurements to specific stability tests for each individual case.


A touchscreen, Wi-Fi support and USB connection provide easy, intuitive operation. These features enable automatic data recording and instant sample and user recognition, as well as PC communication and external memory card support.


The Waterlab meter is a certified device that complies with the latest ISO standards.
