HygroPalm series
The ROTRONIC HygroPalm handheld instrument of the AirChip3000 generation are the perfect instruments for
climatic measurements. They are extremely precise and feature many practical functions, but are easy to use.
HygroPalm are adjusted and configured during production and are therefore ready for immediate use. They can
be configured for specific applications with user-friendly HW4 software or directly on the keypad. A large range of
interchangeable probes enables easy and flexible use, straightforward maintenance and simple calibration.
The HP23 version can be used for the in-situ adjustment of transmitters and for system validation.
For HVAC technicians and inspectors, the pharmaceutical industry, building management systems, the paper industry, research and many others.
