KQT-O2 Electrochemical Oxygen Sensor

1.Overview

The KQT-O2 oxygen gas detection sensor is a battery-type sensor. It generates an electric current through the reduction reaction of oxygen on the working electrode and the corresponding oxidation reaction of the anode material. The magnitude of the current is proportional to the concentration of oxygen. The concentration of oxygen can be determined by measuring the magnitude of the current.

2. Application Fields

1.Oxygen alarms in the mining field

2.Medical oxygen generators

3.Air quality detection instruments

4.Air purification equipment in underground parking lots and commercial areas

5.Air quality detection in vehicles, as well as the fresh air systems of in-vehicle purification equipment
