The MDU420 dual-range methane monitor is a portable instrument designed for use at landfills.
Industrial Scientific Corp.420 dual-range methane monitor is a portable instrument designed for use at landfills. It monitors the percentage volume concentrations of methane in landfill wells and detects the low-percentage LEL gas concentrations that may exist at the perimeter fence line.

Industrial Scientific Corp.420's infrared detector measures on two scales with a single sensor, allowing monitoring of methane concentrations up to 100 percent by volume or from 0-10 percent of the LEL. The instrument can make methane measurements in oxygen-free environments without interference from other landfill gases such as hydrogen sulfide or carbon dioxide. The instrument features:

  • an auto-ranging digital display.
  • an internal sampling pump that draws a vacuum to 100 inches of H2O.
  • a choice of sampling probes to match the application
  • one-button operation and calibration
  • a "Pump Off" mode to conserve battery power
  • optional data logging
  • a self-diagnostic sensor to reduce calibration frequency
