Description
Overview
GAOTek fixed chlorine gas analyzer uses a high-performance intelligent chlorine gas sensor, which is a high-performance instrument that can continuously monitor chlorine gas concentration online. The overall explosion-proof structure of the detector has high sensitivity and precision. The detector can realize real-time concentration display on the computer through the gas alarm controller and monitoring management software. It can also transmit real-time monitoring data and alarm status to the safety control center through the optional wireless module.
