Methane Detectors Landfill Gas and Subsurface

Intrinsically safe Gas-Sentry detectors for measuring methane and optionally oxygen in landfill gas are used for determining the extent of subsurface landfill gas migration and monitoring the safety of ambient air in confined and enclosed spaces.

Checking a Manhole for Landfill Gas

Bright LED Numeric & Alpha Display
High precision numeric display with flashing alpha descriptors indicating which scale is alarming
Two Sensors Provide Accurate %LEL and %GAS
Readings Catalytic combustion and thermal conductivity sensors detect the full range of methane in air
TRACK GAS Scale
High precision with quick response for locating above ground landfill gas.
Automatic Calibration
Catalytic combustion, thermal conductivity, and oxygen sensor automatically calibrate
Optional Bar Hole Probes
Clear plastic, metal, and fiberglass 34 inch long probes are ideal for measuring subsurface landfill gas Optional Water Stopper Water check valve with push button water release for bar holing in wet soils
