Wherever it is necessary to study the shelf life of a product in order to determine its risk of microbial development and therefore its shelf life over time, Waterlab is the ideal solution.
Waterlab is also the most performing instrument on the market thanks to its dew point sensor which measures the actual water activity (aW) and not related and secondary parameters. For this reason the dew point sensor is considered the reference point for these determinations.
New calibration and control modes allow the operator to optimize times even in the case of multiple analysis of samples with very different aW values. Thanks to the introduction of innovative calculation and temperature control systems, Waterlab allows you to carry out different types of analysis: from simple determination of control to specific shelf life tests for each individual case.
Thanks to the latest generation touch screen graphic display, Wi-Fi and USB compatibility, Waterlab guarantees a simple and intuitive work flow allowing automatic data saving and immediate recognition of the sample and the operator as well as the possibility to communicate with a PC and external memory cards.
