Overview
Enviro Test Construct NH3 gas meter is a portable gas detector which can show real-time data and send alarms when the reading reaches the set value. The device is a suction and diffusion dual-purpose instrument. When the pump fails to work, it can automatically switch to the diffusion sampling mode. It also with back clip so the user can conveniently carry it. It is with the data log function. Which is not only able to store data on a device but also transfer data to PC by USB wire. It is IECEX, ATEX explosion-proof certified, and its protection level reaches IP67.
