Product Overview

2004FC-118 R13 (01/14) Emerson Climate Technologies
SP 32
System Protectors
The HMI is designed to provide an accurate method of
determining the moisture content of a system’s refrigerant.
The HMI has a unique high accuracy moisture indicator for CFC,
HCFC, and HFC refrigerants.
Features
• Highest sensitivity moisture indicator available
• Hermetic, leak-free construction
• Single indicator for all common refrigerants
• Accurate color calibration at low ppm levels
and higher temperatures
• Wide angle viewing/high visibility window for ease of
monitoring
• All brass corrosion resistant body for fewer leaks
• Solid copper connections
Specifications
• Maximum working pressure: 680 psig
• UL/CUL le number: SA 9566
