2.1 Installing the Probe in a Sample System
Moisture probes are installed into a portable sample system. The sample
system protects the probes from coming into contact with damaging
elements in the process.
CAUTION!
If you are mounting the moisture probes directly into the
process line, you must consult the factory for proper
installation instructions and precautions.
