MLD Methane

Gas Leakage detector for Methane (CH4)

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 readings are output through Digital: Modbus (RS-485), Dry Contact: 2 Relays (2A) or Analog: 4-20mA..


  • No field calibration
  • No cross sensitivity
  • Long lifetime 15+ years
  • Fail safe (built-in diagnostic)
  • 3-100% LEL
  • Rh compensation
  • Immune to poisoning
  • Operating range -40° to 75° C, 0-100% Rh
  • Modbus, Relays and 4-20mA Output (ALL IN ONE)
