HygroGen2

< 0.1% rh stability
cost effective calibration
calibration over 0 to 60°C

Stable humidity and temperature calibration.

The Hygrogen2 provides a stable environment in which to calibrate any rh & temperature measuring instrument. This system, also available to hire, is a cost effective calibration solution.

Reaching humidity equilibrium in around 5 minutes, the Hygrogen2 can calibrate up to 5 probes simultaneously. The user friendly touch screen has a graphical interface and is capable of setting up to 200 set-point changes per programme with up to 20 programs.

The provision of a heated sample loop for the connection of a chilled mirror instrument allows cross checking with the control HygroClip sensor, and improves uncertainty.

The internal water reservoir incorporates onscreen level monitoring so the user can monitor and control the water level for the duration of a calibration.

An integrated UV sterilisation system within the water reservoir eliminates any issues caused by water-borne contaminants.

The standard Hygrogen2 is supplied with:

touch screen user interface
set-point control and programmer function
heated sample loop
1x desiccant cell
1x fill syringe
embedded HW4-P software.

A variety of chamber doors (ordered separately) are available to suit sensors with different diameters.
