Proégé ZM disposable gas detector is a maintenance-free solution for gas detection which is small and ergonomically designed and easy to use.
It comes in three models; for oxygen (O2), hydrosulphuric acid (H2S) and carbon monoxide (CO). It is activated by a button, has adjustable alarm settings and an easy-to-read display. When you have switched it on the first time the monitor does the rest. Once activated, the gas detector does not need calibration or charging.
It is driven by a Litihum-ion battery and can be used in the field all day, every day for two years. The H2S and CO models have a rest function, to preserve battery function by up to an additional year.
Alarm functions: Red LED, audible signal and vibration alarm.
