The HygroLab 3 is a table top water activity indicator with 4 probe inputs. It features three operating modes:

• AwQuick: accelerated water activity measurement with automatic end of measurement

• AwE: conventional water activity measurement with automatic detection of equilibrium and automatic end of measurement

• Standard: water activity and temperature measurement, limited to just indicating the values and the trend of the values

Up to 4 probes can be run simultaneously in the same mode. The HygroLab 3 is compatible with all the models of HygroClip probes to permit the direct measurement of products in bulk and quality control of packaging materials.

The probes used with the HygroLab 3 indicator can be calibrated and adjusted at one or more points, directly from the instrument keypad. Reference humidity values are provided by using the ROTRONIC certified humidity standards.

When installed on a PC (Windows XP or Vista required), the HW4 software offers additional functions such as the automatic capture of end values, as well as data logging and a live graph.
