Product Description

The HP23 is a multi-function hand-held indicator that can read the data from up to two HygroClip2 probes and display relative humidity, temperature and a calculated parameter such as the dew or frost point.

Full logging functions including spot recording, with time base, multi-point calibration adjustment.

Any probe input can also be configured by the user to accept a third party analogue probe (restrictions apply).

Probe selection is based on the application. Depending on the HygroClip2 probe model, the measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F).

The HygroClip2 probes feature durable sensors, consistent performance and can be hot-swapped to facilitate routine maintenance.

The HP23 indicator offers extensive settings and functions that can be enabled and configured by the user either directly from the keypad or with the ROTRONIC HW4 software.

The measurement results can be recorded continuously and these separated simply using the batch function. All ROTRONIC transmitters in the Airchip3000 series can be adjusted with the HP23-A via a service cable.


Mobile applications in HVAC, the pharmaceutical industry, building management systems, museums and warehouses.
