hygrometer details
Introduction
A general description of the Humilab chilled mirror is presented in
Chapter 4. In most installations this general description is
completely adequate. However, some applications may require
system modification to meet specialized needs. This appendix
describes how to make these changes. It also provides more
detailed information on the Humilab mirror system, its mainte-
nance, and troubleshooting.
Because of the delicate and critical nature of the chilled mirror
components, this information is intended for trained electronics
technicians. If you are not comfortable performing procedures in
this appendix, contact GE General Eastern for assistance.
