Description
Overview
GAOTek Multi-Gas Monitor is a multi-gas detector to measure the concentrations of 6 gases simultaneously. It adopts interchangeable smart sensor modules, easy to replace the sensors and maintenance. It can combine various gases: O2, toxic gases, combustible gases., convenient for the workers to monitor the gas environment in working site. Send alarms when exceeding gas concentration is detected, protesting the workers from danger caused by O2 deficiency, toxicity and explosion.
