HygroGen - Transportable Humidity & Temperature Reference
HygroGen is a completely self contained generator of humidity and temperature.
The primary application is to generate controlled %rH and temperature
conditions over a wide range; users can calibrate probes at the conditions
they require.
Fast equilibrium to set %rH values (typically 2/3 minutes). User can check calibration at several points in a very short time.
Up to five probes can be tested at the same time, allowing users to check multiple probes very quickly.
Integrated temperature control. User can calibrate at the same temperature in the laboratory or on-site, and calibrate at temperatures other than ambient (higher/lower).
Completely self-contained, no external connection except mains power needed for convenient on-site use.
The HygroGen test chamber or working space is key to the products ability to provide a precise and stable reference that any humidity calibration needs.
The careful design and construction means that we are able to achieve temperature control stability of better than 50 milli Kelvin and temperature of 0.1°C.
A further unique feature of the HygroGen chamber is the availability of three HygroClip probe connections points. The control probe is installed furthermost into the chamber and two additional positions in the middle and front mean that internal temperature homogeneity can be observed by the user.
