Introduction
GNL-3000 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
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.
