Stable operation for humidity tester
A new product range is available for measuring relative humidity and associated variables in process and environmental test applications.
The GMP343 weighs less than 400g and consumes less than 1W of power.
The probe uses the unique Vaisala Carbocap silicon-based infra-red sensor.
The diffusion-aspirated design eliminates the need for sampling systems and pumps.
In soil respiration box measurements this design also eliminates errors caused by pressure differences often present in pump-aspirated measurement systems.
The GMP343 is very stable, with 6h drift less than 1ppm outdoors.
The warm-up time is short.
The GMP343 can output numerically filtered or raw measurement data.
Additional features include: heated optics; options for temperature, relative humidity and pressure compensation; and built-in self-diagnostics.
In addition to the diffusion-aspirated version, the GMP343 is available as a flow-through version.
The GMP343 can be powered and used with the portable MI70 indicator for convenient field measurement. Request a free brochure from Vaisala ...
