Description
Overview
GAOTek Online CO Analyzer is an intelligent high-performance analytical instrument that mainly adopts the non-dispersive infrared (NDIR) measurement principle and can continuously monitor multiple component gases on-line. The analyzer is equipped with a 5-inch touch TFT-LCD large color LCD control screen, the overall menu structure is reasonable, the easy-to-understand UI color icon menu, intuitive and friendly user-operated touch interface, all status displays, measured values and alarm values are simulated and provided digitally. The standard 19-inch chassis, rack-mounted, desktop, and wall-mounted are optional. The built-in filter and regulating valve are not disassembled and replaced on site. It is suitable for on-line monitoring of industrial sites and laboratories 24 hours a day.
