HP22 Humidity Temperature Meter

The HP22 is a versatile hand-held indicator that displays relative humidity, temperature and a calculated parameter such as the dew or frost point, based on the measurements of a HygroClip 2 plug-in probe.

Probe selection is based on the application. Depending on the HygroClip 2 probe model, the measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F). The HygroClip 2 probes feature durable sensors and consistent performance. All HygroClip 2 probes can be hot-swapped to facilitate routine calibrations.

The HP22 indicator has an extensive set of settings and functions that can be enabled and configured by the user either directly from the keypad or with the ROTRONIC HW4 software.
