Sanhua sight glasses provide an immediate visual of system liquid condition. Easy to follow green and yellow color indicators alert to dry or wet conditions. When a system has a refrigerant shortage or restriction, the large sight glass allows for easy detection of bubbles. Sanhua Sight Glasses are compatible with common HCFC and HFC refrigerants and are UL approved to a maximum operating pressure of 667 psig.

White Rodgers Cooling Controls moisture indicators are designed to provide an accurate method of determining the moisture content of a system's refrigerant. The HMI is the highest sensitivity moisture indicator available and it detect moisture at 3% relative humidity (RH) providing plenty of time to make necessary adjustments before any damage is done. The Copeland AMI moisture indicator features a take-apart design for easier repair and the A-IHL saddle design moisture indicator is ideal for large diameter tubing.

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
• Solid copper connections
• All brass corrosion resistant body for fewer leaks
