GNL-6900 Online Wide Range Oxygen Analyzer
-
The invention integrates a digital proportional valve with Chang Ai’s patented technology, combining all functions and characteristics of both the oxygen analyzer and the digital proportional valve.
-
PID control adjusts the opening of the digital proportional valve to regulate the charging flow process, achieving and maintaining the oxygen concentration range required by the measured environment.
-
Data storage function: records data in a timely manner, allowing users to quickly search stored records.
