The HygroLab features two distinct operating modes:
•Aw Measurement: This specialized mode is used for measuring the water activity (Aw) of product samples and materials in bulk such as powders, seeds, etc. When set to operate in the water activity mode, the HygroLab automatically displays humidity as Aw (1.000 Aw = 100 %rh). The Aw Mode offers the following options:
➢Accelerated water activity measurement (AW Quick): permits measuring the water activity of most products in typically 5 minutes. The measurement starts simultaneously for all four probe inputs and is ended automatically.
➢Conventional water activity measurement (AWE): the measurement starts simultaneously for all four probe inputs. The HygroLab automatically detects full equilibrium conditions and ends the measurement at that time.
•Adjustment (This features are only available with the Software Version 2.0.0.0 or higher)
➢Relative humidity: Multiple point calibration and adjustment
➢Temperature: One point calibration and adjustment
•Standard Mode: In this mode the HygroLab can be used as a general-purpose indicator with the following functions:
➢Relative humidity and temperature data measured by up to 4 HygroClip 2 digital probes
The HygroLab is available with a wide assortment of HygroClip 2 humidity-temperature probes to meet almost any requirement. The HygroClip 2 probes feature well proven, durable sensors. Digital signal processing ensures consistent product performance and also facilitates the task of field maintenance with features such as potentiometer free – digital calibration.
