Description
The Copeland 065397 Hermetic Moisture Indicator (Model HMI-1FM3) is a precision-engineered sight glass and moisture detection tool designed for use in hermetic refrigeration and air conditioning systems. With a 3/8″ female flare inlet and 3/8″ male flare outlet, this indicator installs easily into existing liquid lines without the need for special adapters, providing a quick visual check of both refrigerant flow and system moisture content.
Rated to a maximum working pressure of 680 PSI, the HMI-1FM3 is built to handle the demands of modern high-pressure refrigerant systems. Its broad refrigerant compatibility — covering CFC, HCFC, and HFC refrigerants — makes it a versatile choice for a wide range of commercial and residential HVAC/R applications.
The color-changing moisture indicator element gives technicians an immediate, at-a-glance reading of system moisture levels, helping to prevent acid formation, compressor damage, and premature system failure. Regular monitoring with the HMI-1FM3 supports proactive maintenance and helps extend the service life of the entire refrigeration circuit.
