Trace Oxygen Transmitter GNL-J3

Trace Oxygen Transmitter GNL-J3

TraceOxygen Transmitter GNL-J3

The GNL-J3 oxygen transmitter uses an advancedimported fuel cell type oxygen sensor, intelligent micro control technologycircuit and SMD parts. It measures the oxygen concentration without benchmarkgas and has such observable characteristics of high precision, long life, smallappearance, lower power loss and simple operation.

Features
1. The GNL-J3 oxygen transmitter measures oxygen concentration in H2 or deoxidizegas.

2. The inner special protection gas-route protects the sensor when it isexposed in the air for a long time by turning off the power or cutting off thegas-route automatically.

3. It has automatic temperature compensation, eliminating the impact ofenvironmental temperature.

4. The GNL-J3 oxygen transmitter can be connectedto a computer via the standard RS232 or RS485 interface.

Applications

It can be used to measure the trace oxygenconcentration in nitrogen separation from air, chemical process, magneticmaterials such as high temperature sintering furnace gas protection, theelectronics industry protective gas, glass and building materials industries,various mixed gases, and so on.
