Rotronic HP22 HygroPalm Humidity Temperature Handheld Indicator

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.

Selecting the appropriate probe model from the HP22 probe options is done based on the application. Depending on the probe model, the measuring range is within 0 to 100 %RH and -100°C to 200°C (-148°F 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 configured and enabled by the user with the ROTRONIC HW4 software. In spite of its sophistication, the HP22 can still be used just as a simple humidity and temperature indicator. Whether you decide or not to take advantage of its full potential, the HP22 will let you have it your way.
