Online Gas Detector Oxygen and Carbon Dioxide Dual Meter Analyzer for Laboratory

Product Description

Online Gas Detector Oxygen and Carbon Dioxide Dual Meter Analyzer for Laboratory
I. General Principles
This solution is applicable to the online monitoring system of oxygen and carbon dioxide concentration in the environment of Party A's equipment. This system can sample and detect the concentration of oxygen and carbon dioxide gas in the production process in real time, and provide the detected gas content to the user in the form of 4-20mA current signal, which is used to realize automatic control and analysis of system process, etc.
