The MGS-400 series product family uses three different sensor types, depending on the measurement range, temperature and gas types when detecting for hazardous refrigerant leaks, the communiqué said. The variety of sensor types within the product line offers significant user benefits, including flexibility with refrigerant leak detection and providing peace of mind when helping to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378 inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk-in freezers, the communiqué said.

Other user benefits, the communiqué said, include a mobile app interface for easy commissioning and maintenance without special tools and an added sensor life of 5-7 years with plug-and-play pre-calibrated sensor modules for quick, simple sensor replacement. According to the communiqué, generating calibration certificates from the mobile app makes calibration documentation easy to create and send by email or store in the cloud. A Modbus RTU interface, the communiqué said, and analogue and relay outputs enable easy safety alarming and automation control.
