Water Activity Measurement from 0.00 to 1.00aw - A water activity Meter for  Production, R&D and QA 

The LabMaster using the latest version of the Novasina Resistive Electrolytic measurement cell , processes tests under tight temperature control. This widens the calibration and measurement range from 0.00 to 1.00. It allows measurementscompliant with most industry and international standards.

Some of the special capabilities of the instrument include a slot in the temperature controlled chamber for the next sample (preheating it to the test temperature), coverage of powder, gel, liquid and solid samples, adjustable stability parameters, control of up to 9 LabPartner test stations, built in test analysis software, printer output and development of sorption isotherm curves.

The  instrument provides high volume production testing, quality assurance data and analysis and product development/R&D tests.
