HygroGen2 Chamber and Door
The HygroGen2 does not come supplied with a door. There are various standard and customized
versions available, depending on the intended use for the instrument, the use of an external reference
(see Appendix A1.2 ) and the instruments under test. Figure 1(6) above shows the 15mm 5-port version
(part code: HG2-D-11111). Other options are listed in Appendix B4 .
To access the HygroGen2 chamber, remove the door. Grip firmly and twist the door anti-clockwise. In
the event that this proves difficult, cool the chamber first. Occasional application of silicone grease
around the door “O” ring seal will ease movement.
