A new portable for measuring relative humidity has dual probe operation plus chemical purge and sensor pre-heat option
The Vaisala HM70 is designed for measuring relative humidity and temperature in chambers and other demanding applications where accuracy is important.
The hand-held meter is robust, has a graphical LCD display for trend monitoring and can function as a data-logger.
Optional software provides a simple ready-to-use interface to a PC.
A sensor purge option helps maintain accuracy in applications where high concentrations of chemicals are present.
The pre-heat feature reduces measurement delays by keeping the sensor dry when the probe is inserted into hot and humid processes.
The meter comes with a choice of probes for use in temperatures from -70C to 180C.
Two probes can also be connected into the meter at the same time and a humidity difference display obtained.
This simplifies environmental chamber profiling for example.
