Product Description
Introduction
GNL-J3 oxygen transmitter adopts advanced imported fuel cell type oxygen sensor, intelligent micro control technology circuit and SMD parts. It measures the oxygen concentration without benchmark gas and has such observable characteristics of high precision, long life, small appearance, lower power loss and simple operation.
Features
Measuring oxygen concentration in H2 or deoxidize gas
Inner special protection gas-route protects the sensor when it exposures in the air for a long time by out of power or cutting off the gas-route automatically.
Automatic temperature compensation, eliminating the impact of environmental temperature
Connected to a computer via the standard RS232 or RS485 interface
