PS-7

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 selection of high-quality, detectable gas sensors are available.

The PS-7 is compatible with the EC20x Multipoint Gas Detector Cabinet for customing a complete TGMS. Please contact us to review complete factory-installed options.

Lead times vary by item. A shipment/delivery estimate will be provided upon placement of your order. Please contact us to review your delivery requirements before requesting expedited shipping for rush delivery.
