Rotronic HP23-A Humidity Temperature Handheld Indicator

DISCONTINUED ITEM-Recommended Replacement: Rotronic HP32 HygroPalm Humidity Temperature Handheld Indicator

The HP23-A is a multi-function hand-held indicator that can read the data from up to two HygroClip 2 probes and display relative humidity, temperature and a calculated parameter such as the dew or frost point. Any probe input can also be configured by the user to accept a third party analog probe (restrictions apply).

Selecting the appropriate HygroClip 2 probe for the HP23-A is done based on the application. Depending on the probe, 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, consistent performance and can be hot-swapped to facilitate routine maintenance.

The HP23-A 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. In spite of its sophistication, the HP23-A 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 HP23 will let you have it your way.

The HygroPalm23 is ideal for all applications where precise measurement of humidity and temperature is required e.g. the food and pharmaceutical industries, printing and paper industries, the sciences, meteorology, agriculture, climatology and many more. There is hardly a field in which these parameters may be ignored. It is ultimately the measuring task at hand that defines the HygroPalm instrument and probe that best meets your needs.
