- Model HP22-A - HygroPalm - HP22-A - Versatile Handheld Indicator


The HP22 is a versatile hand-held indicator that displays relative humidity, temperature and a variety of calculated parameters such as dew or frost point based on the measurements of a HygroClip2 plug-in probe. 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 and consistent performance. All HygroClip2 probes can be hot-swapped to facilitate routine calibrations. The HP22 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. Applications Mobile inspection and random tests in HVAC, the pharmaceutical industry and building management systems

probe for environmental measurements, and with the

probes for measurement in ducts or high temperature applications. Thanks to the digital interface between the HygroPalm handhelds and the HygroClip probes, the instrument can be easily applied to a wide variety of other applications such as paper, food, powders and granules. Measurements can also be displayed on the backlit LCD in terms of dew/frost point, with other parameters and functions available, including the transfer of probe log data, when connected to a PC running HW4 software.
