Description
Overview
GAOTek Portable VOC Gas Analyzer with Alarm is a gas detector that adopts a high-performance intelligent hydrogen cyanide gas sensor. It is a portable handheld detection instrument that can continuously monitor hydrogen cyanide gas concentration. The detector uses more than 30 kinds of plug-and-play smart sensors, including imported PID photo ion sensor, electrochemical poison gas sensor, catalytic combustion sensor, infrared sensor, and TCD thermal conductivity to adapt to different testing needs for different industries.
