PS-8M Single-Point Gas Detector (Standard Main Unit) The versatile PS-8 Single Point Gas Detector monitors a wide range of toxic and combustible gases, as well as oxygen depletion. This reliable system employs electrochemical, hot-wire and galvanic detection principles utilizing gas-specific sensors.
The PS-8 offers over 125 designed gas calibrations with measurements in PPB, PPM, % LEL and O2 volume. The device can extract a sample from up to 75 feet away with a robust pump lasting up to seven years. Add a compact and reliable low-temperature pyrolyzer for NF3 monitoring.
A vast selection of replaceable gas sensors are available. The PS-8 uses the same quality, interchangeable sensors as its predecessor (PS-7), which can distinguish between combustibles.

The PS-8 is compatible with the EC20x Multipoint Gas Detector Cabinet for customizing a complete TGMS. Please contact us to review more factory-installed options.
