The first aW meter made in Italy


Waterlab represents the "state of the art" of water activity measurement (aW) and today is an indispensable tool for quality control of products and ingredients in the food, pharmaceutical, cosmetic and herbal sectors. Whenever it is necessary to study the shelf life of a product in order to determine the risk of microbial development over time, WATERLAB is the ultimate solution.

Waterlab is also the best performing aW instrument currently on the market thanks to its dew point sensor which allows to measure the real water activity (aW) and not related or secondary parameters.

New methods of determination enable operators to optimize analysis times even in case of samples with very different water activity (aW) concentrations.

Advantages

Waterlab is the only water activity analyzer equipped with dew point sensor integrated with a colour touch screen graphic display. Measurement by means of a dew point sensor ensures maximum sensitivity and analytical selectivity in about 5 minutes.

Possibility to calibrate the instrument with different standards at the same time or with one standard at a time. Multi-point calibration allows for real adjustment of the calibration curve.

WATERLAB allows thermostating of the sample from 15 to 50°C, and can be set as desired as well as programmed automatically for accurate shelf life study.

WATERLAB is the best performing aW instrument thanks to its dew point sensor which measures the real free water activity (aW) and not other interfering and unwanted substances with an accuracy of + - 0.003 aW.

Thanks to the state-of-the-art graphic touch screen display, wi-fi and usb compatibility, Waterlab guarantees a simple and intuitive workflow allowing automatic data saving and immediate recognition of sample and operator as well as the possibility of communicating with an external PC and printers.

Dew point sensor


By using dew point technology aW is determined when the thermal equilibrium between the water liquid phase present in the sample and the vapour phase water in the headspace is achieved by measuring the temperature of the mirror at the time of dew point formation.
The most accurate, fastest and reliable sensor, in compliance with ISO 18787: 2017 regulation.
WATERLAB has a sensor block with front opening for easy sample placement and cleaning.
It is aslo equipped with a fan ensuring homogenous conditions and with a highly sealed chamber that prevents environmental interference.

The dew point sensor combined with a 7" touch screen graphic display allows for analysis speed and accuracy as well as user-friendly operations and data flow.
