Gas Detectors for Fire Departments and Fire Rescue

Intrinsically Safe Gas-Sentry detectors for combustible gas and oxygen with optional sensors for carbon monoxide, and hydrogen sulfide are used for residential CO inspections and testing the safety of ambient air during post fire overhaul and confined space entry, and locating leaking gas or accelerants.

Locating Leaking Combustible Gas

Bright LED Numeric & Alpha Display

High precision numeric display with flashing alpha descriptors indicating which scales are alarming

Full Range of Gas on %GAS and %LEL Scales

Catalytic combustion and thermal conductivity sensors detect the full range of combustible gas

TRACK GAS Scale

High precision with quick response for locating leaking combustible gas

Automatic Calibration

Catalytic combustion, oxygen and CO / H2S sensor automatically calibrate in 30 seconds

Optional Calibration Verification

Docking stations automatically supply calibration gases and record calibration data

CO / H2S Sensor

Toxic gas (CO / H2S) sensor which is CO specific when used with in-line interference filter
