The Rotronic HygroPalm22-A measurement range (depending on probe model - sold separately) is from 100 to 200 °C (-148 to 392 °F) and 0 to 100 %RH.
The HP22-A is an indicator that displays humidity, temperature and a calculated parameter. This is based on the measurements of a HygroClip 2 plug-in probe - sold separately. The measurement range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F) depending on the HygroClip 2 probe model. All the HygroClip 2 probes can be hot-swapped to encourage routine calibrations. This indicator has a broad 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.
