Recommended Installation
GMP231 is designed to be installed through a chamber wall, and attached
to the chamber chassis using an attachment bracket and the two screw
holes on the side of the probe. As the installation depth of the probe
inside the chamber is critical (see section Probe Installation Depth on
page 21), the mounting method must allow the probe to be positioned
exactly.
NOTE The probe and electronics housing must remain outside the heated
chamber. The electronics housing should be in a ventilated space that is
open to ambient air.
