Description
Overview
The GAOTek handheld nitric oxide gas detector – Standard storage function 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 is also with back clip so user can conveniently carry. It is IECEX, ATEX explosion-proof certified, and its protection level reaches IP67. It is with data log function, which is not only able to store data on device but also transfers data to PC by USB wire.
