Introduction to Purity oxygen analyzer                                                                               

GNL-2100L purity oxygen analyzer breaks through traditional magneto mechanical measurement and achieves to measure oxygen concentration without benchmark gas by adopting conversion ion current with the world advanced technology as measurement principle. It has observable characteristics of long calibrating period, high precision, small appearance, low power consumption, etc.


Features of the purity oxygen analyzer                                                                                

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

2.High precision, automatic temperature compensation, eliminating the impact of environmental temperature.

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

4.AC-DC power supply, using neatly. Full charging battery can continually about 8 hours

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

6.Inner air pump(option)
