Rotronic : HP22

The HP21 interfaces with the standard HC2-S probe for environmental measurements, and with the HK25/HK40 probes for measurement in ducts or high temperature applications.

Thanks to the digital interface between the HygroPalm handhelds and the HygroClip probes, the instrument can be easily applied to a wide variety of other applications such as paper, food, powders and granules.

Measurements can also be displayed on the backlit LCD in terms of dew/frost point, with other parameters and functions available, including the transfer of logged data, when connected to a PC running HW4 software.
