Multi Zone - Gas Leak Monitor MZ

incl. VAT, plus delivery


Multi-Zone Gas Leak Monitor MZ

The refrigerant leak monitors of the MZ (Multi-Zone) series impress with their outstanding performance, flexibility and functionality in the continuous monitoring of refrigerants. The high-tech NDIR sensor can detect the lowest concentrations of up to 1ppm.

  • High-precision and durable infrared sensor
  • No cross-sensitivity to temperature, humidity or other gases
  • The sensor does not require calibration, but due to legal requirements, the calibration must be checked.
  • The high-precision sensor detects smallest concentrations of 1 ppm and thus helps to detect leaks earlier and faster, so that energy can be saved
  • Fast response time despite distant monitoring areas (up to 365m)
  • Display of the current concentration on the large LCD display
  • Up to 16 monitoring areas, expandable by splitters to 48.
  • MODBUS Communication
  • Optional Remote Display
  • HGM-MZ - Halogen-containing refrigerants with a library of over 60 gases. Different gases can be detected in the different monitoring areas
  • AGM-MZ - Ammonia NH3 / R717 Monitoring
  • CO2-MZ - Carbon Dioxide CO2 / R744 Monitoring

Top quality refrigerant leak monitor

The HGM-MZ model detects halogen-containing refrigerants lie CFC, HCFCs and HFCs. The HGM-MZ has a built-in library of more than 60 refrigerants for this purpose. The AGM-MZ can be used for NH3 ammonia monitoring (R717) and the CO2-MZ is used for CO2 carbon dioxide monitoring (R744).

The multi-zone devices convince not only because of the performance and functionality, but also in terms of acquisition and maintenance costs. The HGM-MZ can detect over 60 refrigerants and complies with the specifications of ASHRAE 15-2007 as well as the European standard EN 378 and F-Gas.

Continuous monitoring of up to 16 monitoring areas, so-called zones, is no problem and measurements can also be stored. The meter can be equipped with a 2-channel 4-20mA output. Three alarm relays are installed so that external alarm signals can be triggered. The measuring device has an acoustic alarm as well as a visual alarm that is triggered at the threshold values (leak, spill, evacuation) or in the event of an error.

In the course of monitoring, only minor maintenance work is required, such as the replacement of filters.
