8 Technical data
8.1 Specifications
General HygroLab C1
Device type
Humidity-temperature bench-top indicator with 4 probe inputs
(HygroClip 2 digital probe) and real time clock (date and time)
Power
Model AC1211 power adapter (100…240 VAC – 12 VDC, 200 mA).
The USB interface can be used to power the HygroLab C1 (no power
adapter required - current draw: about 70 mA). Use of the Ethernet
interface always requires a power adapter.
