Introduction
GNL-2100L 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
New pattern, long-life, conversion ion current tester with fast response and high sensitivity
High precision, automatic temperature compensation, eliminating the impact of environmental temperature.
Checking the sensor working state automatically and unique double-line working change mode extending the sensor's life
Setting upper and lower alarm values freely during the measure ranges
AC-DC power supply, using neatly. Full charging battery can continually about 8 hours
It can achieve two-way communication by connected to a computer via the standard RS232 or RS485 interface.
Inner air pump(option)
