The Rotronic HygroPalm23-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 HP23-A is an indicator that can read the data from up to two Hygroclip 2 probes and display relative humidity, temperature and a calculated parameter. The probe input can be configured by the user to acknowledge a third party analog probe. The measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F) depending on the HygroClip 2 probe model - sold separately. The indicator has a far reaching 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.
