Since its launch, HygroGen has become the benchmark for transportable RH and temperature calibrators. Hundreds of users worldwide have identified that this tool for rapid generation of fixed humidity and temperature conditions can save significant amounts of time when performing RH and temperature calibrations. The pharmaceutical industry especially has embraced the HygroGen’s capability to calibrate over an instruments working range to satisfy the stringent demands of Quality and Compliance regulations. The ability to transport the HygroGen to the installation location means that a complete system qualification is possible.

The second generation HygroGen builds on the excellence of the first series with higher specifications, additional features and improved design. Using a state-of-the-art embedded controller with touch screen user interface has been developed to provide the user with simplified setup and configuration tools. This includes a programmer function so that multiple set-point changes can be user defined. The embedded platform also provides additional features such as an integrated nine port USB hub, external DVI monitor connection, integrated data acquisition and calibration adjustment software. The design objective was to create the perfect balance of form and function – precise generation of stable conditions, whilst being easy-to-use and maintain.

HygroGen2 has a control range of 0.60 °C.
Improved mechanical design provides better thermal performance in terms of speed of response, control stability and temperature gradients.
Temperature control stability at equilibrium is better than or equal to ±0.05 K.
Humidity generation is by a piezoelectric element with digital PID control allowing optimised response across the temperature range.
At equilibrium RH control is better than or equal to ±0.1 %rh.
The internal water reservoir now incorporates onscreenlevel 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.
