Proton® ZM Single Gas Zero Maintenence Monitor

The Proton ZM personal gas monitor provides up to two years of continuous, economical, and zero maintenance-free protection from exposure to Hydrogen Sulfide (H2S) or Carbon Monoxide (CO). Because there are no sensors to replace, or calibration required, you will experience zero downtime.

The Proton ZM monitor provides a bump alert warning with a “Test” message on the display to remind users to “bump” the monitor with gas to verify the performance of the sensor and electronics. This procedure is quick and easy and resets the “Test” message. Using the automated test station makes bump testing quick, simple and cost effective.
