HygroGen
Overview

The HygroGen humidity temperature generator uses a mixed flow method for generating the humidity (%RH) required by the user. A desiccant cartridge provides low humidity, a saturator high humidity, and a control system mixes these together to create a constant environment within a well insulated chamber. Temperature is controlled with a Peltier thermoelectric heat pump. Set points are easily adjusted using the front panel controller keypad, or via the RS-232 interface using a PC and optional controller software.
The HygroGen uses a high performance controller to achieve both exceptional stability and rapid stabilization when moving from one condition to another. Smart chamber design, combined with a high rate of air flow, contributes to minimizing humidity and temperature gradients inside the chamber, and to shielding the chamber from the outside environment.

For the purpose of controlling conditions inside the chamber, humidity is measured with a HygroClip S digital probe and temperature with a separate Pt100 RTD. Depending on the model of HygroGen, the reference humidity and temperature used to calibrate humidity instrumentation is usually provided by another set of probes and instruments
(see calibration traceability).

Key Features

1 Dryer cell - removable cartridge filled with a molecular sieve desiccant (can be regenerated)

2 Distilled water tank. Fill or empty by inserting the dosing syringe in the access port located on the front of the unit

3 Multi-loop controller especially configured and tuned for the HygroGen

4 Internal chamber designed to provide a stable calibration environment with minimal temperature gradients.

5 Chamber door - different models available

6 Stainless steel enclosure - facilitates cleaning
