Description


MLD methane detector

MLD gas detector for methane based on NevadaNano MPS Technology

The MLD gas detectors for methane provides quick and accurate detection of methane across a variety of industries — from the oil and gas supply chain to safety applications. The smart sensor is intrinsically safe, robust, and extremely poison-resistant.
It has built-in environmental compensation and self-testing for fail-safe operation. 
Sensor output are available through Digital: Modbus (RS-485) and Analog: 4-20mA and Analog: 0.4-2V and 2x Dry Contacts: Alarm Relay for LOW conc. - Alarm Relay for HIGH conc./FAULT 
MLD Extended Range Methane detector is designed and optimized for open-air detection of methane and natural gas plumes over a full range of concentrations, from 50 to 1,000,000 ppm.
Note: the MLD Extended Range Methane is not suited for safety applications or for detection of gradually accumulating concentrations (e.g. slow leaks into confined, poorly ventilated spaces).
