GD-3000 Gas Detector - Combustible Gas Detector/Controller/Transducer/Hydrogen, Propane or Methane Gas Detection   GD-3000
Combustible Gas Detector/Controller/Transducer
Hydrogen, Propane or Methane Gas Detection
  The GD-3000 is a versatile, easy-to-use device that allows you to select between methane, propane or hydrogen gas detection. It provides low-level detection of combustible gas in an easy-to- maintain monitor that is factory calibrated for simple installation. This low voltage detector provides automatic feedback and fan control that can help reduce combustible gas concentrations in battery rooms, parking garages, maintenance facilities, and other locations that require combustible gas detection.
