The versatile PS-7 Single Point Gas Detector monitors a wide range of toxic and combustible gases, as well as oxygen depletion. This reliable system utilizes four different detection principles (electrochemical, hot-wire, galvanic, catalytic bead) and target gas-specific sensors. The device can extract a sample from up to 75 feet away with its robust pump that lasts up to seven years. Add a compact and reliable low temperature pyrolyzer for NF3 monitoring. A vast seletion of high-quality, detectable gas sensors are available.
