A moisture indicator is a crucial component in refrigeration and air conditioning systems designed to detect the presence of moisture in the refrigerant. It typically consists of a sight glass with color-changing indicators that signal the moisture level. Monitoring moisture is crucial because excess moisture in the system can lead to various issues, including corrosion, reduced efficiency, and potential damage to components. The moisture indicator provides a visual indication to technicians, helping them assess and address moisture-related concerns during system maintenance. This enhances the overall reliability and performance of the refrigeration or air conditioning system. 

‘Dry All’ moisture indicator is compatible with CFC, HCFC and HFC refrigerants.
