GMI PS1 single gas monitorGas Measurement Instruments (GMI), an IST company, introduces its new maintenance-free PS1 Series single gas monitor designed with industry leading features. Both lightweight and easy to use, the device offers sensor options for monitoring hydrogen sulphide, oxygen, carbon monoxide, or sulphur dioxide. 

The self-monitoring device features on/off capability and field adjustable alarm settings. During hazardous conditions users are alerted via three alarm functions: vibration, red flashing LEDs and audible buzzer.  The instrument is fitted with a robust stainless steel alligator clip that attaches easily onto a collar or vest, putting the instrument near the breathing zone for maximum protection and safety.

Also available is the new PS1 auto bump and calibration station that provides a fast visual indication that an instrument is calibrated correctly, thereby improving compliance, record keeping, efficiency, and accuracy. Easy to operate, simply place the PS1 into the cradle and close the door. Calibration is complete in 90 seconds and bump testing in 60 seconds. The unit requires minimal effort by users.
