CHANG AI aligns with SOP (Standard Operating Procedure) in production process.
CI-PC1208 Multi-channel Oxygen Analyzer Product Features
With the core of micro-controller, it is stable and reliable, using the frequency conversion ion flow sensor as the measuring unit, with high precision and long calibration period;
It adopts Modular design, oxygen module is added freely, and the number of sampling channels can be chosen between 2-12;
Up to 12 CI-DPR200 digital proportional valves can be connected to control the flow of nitrogen in the corresponding area of the oxygen module to reduce the cost of gas users.
