Intrinsically Safe Gas-Sentry Detector for HVAC Contractors and Plumbers

Intrinsically Safe Gas-Sentry Detectors for natural gas and propane detection with optional sensors for carbon monoxide, hydrogen sulfide, and oxygen are used for residential CO checks, testing the safety of ambient air, leak locating, and testing flue gas for CO.

Testing Flue Gas For CO

TRACK GAS Scale

High precision with quick response for locating leaks Full Range of Gas on %GAS and %LEL Scales
Catalytic combustion and thermal conductivity sensors cover full range of natural gas

Automatic Calibration

Catalytic combustion, oxygen, and CO sensor automatically calibrate in 30 seconds Optional CO / H2S Sensor
Toxic gas (CO / H2S) sensor which is CO specific when used with in-line interference filter

Optional Oxygen Sensor

Three year oxygen sensor measures O2 deficiency and excess in ambient air

Optional Probes

Gooseneck, bar-hole, and flue gas probes to fit the job
