HygroLab 3: general purpose indicator with water activity functions
Same as HygroLab 2, except for:
- Accelerated water activity measurement with up to 4 probes (AwQuick mode): allows the
measurement of most products in typically 5 minutes
- Full equilibration measurement with up to 4 probes (Standard mode) with automatic
detection of equilibrium conditions
- Analog probe inputs with 12-bit resolution

2 General description
2.1 Power requirements
The HygroLab operates with an external AC adapter providing 9 to15 VDC, 100 mA. The power
receptacle is a 3.5 mm Jack female with DC+ center.
Note: when equipped with the optional Ethernet module, the HygroLab requires an AC adapter
able to provide 300 mA.

1) Unless otherwise specified when ordering, all probe inputs are factory programmed to accept a HygroClip
digital probe and the voltage powering the probe is the AC adapter voltage (12 VDC nominal). Prior to using
any analog probe, the corresponding probe input should be re-programmed. With the HygroLab 2 and 3, this
can be done with the HW4 software after connecting the RS232 port of the HygroLab to a PC (see separate
software manual).
