Honeywell m-700051 Airscan Ir R407a Leak Sensor 0-500 Ppm

Product Description

The HONEYWELL m-700051 is a continuous, real-time infrared refrigerant leak detection sensor designed for commercial refrigeration environments. It monitors R407a refrigerant concentrations in the 0 to 500 ppm range and is housed in a commercial-grade enclosure. This unit is CARB compliant, making it suitable for use in California and other regions with strict air quality regulations. Licensed refrigeration technicians and commercial HVAC-R service professionals install and commission this type of sensor as part of a facility leak detection strategy.

This sensor is built for demanding food retail and cold storage applications including retail food storage chillers, refrigerator display cases, freezers, and walk-in coolers. It is intended for installations where continuous refrigerant monitoring is required to meet safety, environmental, or regulatory compliance standards. The commercial enclosure construction suits it for the temperature cycling and humidity exposure common in these environments.

Key Features

• Infrared detection technology provides continuous, real-time R407a refrigerant monitoring
• Detection range of 0 to 500 ppm suits commercial leak threshold requirements
• Commercial enclosure rated for food retail and cold storage environments
• CARB compliant for use in California Air Resources Board regulated applications
• Suitable for retail display cases, walk-in coolers, freezers, and chillers

Compatibility

Designed for use with R407a refrigerant systems in commercial refrigeration applications. Specific compatible equipment or control panel pairings were not provided in the product data; consult the manufacturer documentation to confirm integration with your leak detection system.

Installation Notes

Installation should be performed by a licensed HVAC-R technician or refrigeration mechanic familiar with commercial refrigerant detection systems. Power down the detection system before wiring or removing any sensor components. Follow local electrical codes and the manufacturer wiring diagram when connecting the sensor to the control panel or building management system. Sensor placement height should follow refrigerant vapor density guidelines for R407a to ensure accurate detection.
