Rotronic HW4 Specifications

HUMIDITY PROBES

HygroClip2 probe

The HygroClip2 is a completely new type of probe in a class of it's own in terms of accuracy and

performance. Thanks to the new AirChip3000 technology, it also boasts a unique calibration and

adjustment process as well as many other superb innovations. At the same time ROTRONIC has taken

humidity measurement technology to a whole new level of performance and reliability: the HygroClip2

offers you the best possible reproducibility and a superb system accuracy of < ±0.8 %rh and ±0.1 K.

The new HygroClip2 is available in various formats: from a simple plug-in probe for handheld

instruments and data loggers to the highly developed cable probes for high temperature and other

special applications, we can provide you with exactly the right probe to suit your needs. As standard,

they all have high accuracy, which can be increased further by specific adjustments within our

patented AirChip, making every probe in our range a high-end product for all applications.

Applications

For HVAC monitoring & control, the pharmaceutical industry, building management systems, the

paper industry, research, museums and many others.
