GMI PS1 Single Gas Detector

This product is now obsolete. The closest alternative is the Protege ZM Single Gas Monitor.

The PS1 monitors a single gas, for a variety of applications. Widely used in the oil and gas industry, this rugged, extremely lightweight and accurate monitor clips easily onto a collar or vest. This puts the instrument near the breathing zone for maximum user protection and safety. Audible, visual, and vibrating alarms alert the user, should gas be present and alarms can be latching until the user acknowledges that an alarm is present.

The PS1 Bump Test and Calibration Station is designed to give a fast visual indication that instruments are calibrated correctly. Just place the instrument into the cradle, close the lid. Calibration is complete in 90 seconds and bump testing in 60 seconds. Results can be easily extracted for Calibration Certificate printing at your convenience.

Manual bump testing and calibration is also possible and only requires a cylinder of test gas and regulator. A manual calibration can be perfomed in less than two minutes with results stored on the PS1.
