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
