Replacement can be in any position and requires only a gentle clockwise twist.
Before using your HygroGen2, make sure that the door is secured and that all probe apertures not in
use are sealed with a bung (see Figure 1(7) above) or an appropriate alternative seal.
Desiccant Cell
The unit should be supplied with the desiccant cell in place (Figure 1(5) above). For further details and
best practice for desiccant handling, please see section 8.2 .
External Sample Loop
Unless an external sampling system is to be used (see “External Sample Loop Operation” in Appendix
A1.3 ), ensure the sample loop caps (Figure 2(1) and (2) above) are firmly secured.
HygroClip Control Probe
The HygroGen2 chamber conditions are monitored and controlled by a ROTRONIC HygroClip RH and
temperature probe. Depending on the circumstances and external references employed (see Appendix
A1.2 External RH Probe Reference ), this probe may be removed for regular calibration (see section 8.1
Control HygroClip Calibration ).
Note: For speed of response, this probe must be employed without protective filters.
