Ma-line MA-MMD3EA Lcd Moisture Indicator

Product Description

The MA-LINE MA-MMD3EA is an LCD moisture indicator designed for use in refrigeration and HVAC systems. Moisture indicators allow technicians to monitor the moisture content of refrigerant in a system at a glance, providing a visual confirmation of dry or wet conditions in the refrigerant circuit. This type of sight glass accessory is a standard diagnostic tool used during service, commissioning, and ongoing maintenance of refrigerant systems. It gives technicians a quick, reliable read on system moisture levels without requiring additional instrumentation.

The MA-MMD3EA is suited for use in refrigerant line sets where moisture monitoring is required. Residential and light commercial HVAC and refrigeration systems commonly use inline moisture indicators to detect contamination that could damage compressors or expansion devices. It is sold as a single unit and is installed by licensed HVAC-R technicians as part of routine system maintenance or new equipment installation.

Key Features

• LCD display provides a clear, readable moisture condition indication
• Designed for inline installation in refrigerant circuits
• Sold as a single unit for individual system service
• Supports quick visual moisture assessment without additional tools

Compatibility

Designed as an OEM-style replacement or service component for refrigerant systems requiring inline moisture indication. Consult the manufacturer for specific refrigerant type and line size compatibility before installation.

Installation Notes

Installation of refrigerant-side components must be performed by an EPA Section 608 certified HVAC-R technician. The system must be properly recovered and the refrigerant circuit depressurized before any inline component is installed or replaced. Follow all applicable local codes and manufacturer instructions for brazing, flare, or compression fittings as appropriate to the line set. Verify moisture indicator orientation per manufacturer guidelines to ensure accurate readings after system recharge.
