Measure oxygen purity without needing benchmark gas
High accuracy: 10.00%~99.999% O2
Online high purity oxygen analyzer


CI2000-CY online high purity oxygen analyzer is the online intelligent measurement instrument, which breaks through traditional magneto mechanical measurement mode and achieves to measure the oxygen concentration without benchmark gas by using solid electrolyte frequency conversion ion current oxygen sensor and oxygen pump.


Features of CI2000-CY Online high purity oxygen analyzer

* New pattern, long-life, conversion ion current tester with high sensitivity and fast response

* High precision, automatic temperature compensation, eliminating the impact of environmental temperature

* Concise menu, simple operation

* Checking the sensor working state automatically and unique double-line working change mode extending the sensor's life.

* Automatic data storage in a certain interval time, and browsing data at any time

* Big screen DOT-matrix LCD, showing oxygen concentration, date and time synchronously

* Setting upper and lower alarm values freely during the measure ranges

* It can achieve two-way communication by connected to a computer via the standard RS232 or RS485 interface.
