RKI GX-2003 Multi-Gas Monitor O2 Sensor

RKI GX-2003 Multi-Gas Monitor O2 Sensor monitors oxygen (O2) levels

Replacement oxygen (O2) sensor for RKI GX-2003 multi-gas monitor.

The O2 sensor is a galvanic type of sensor. A membrane covers the cell and allows gas to diffuse into the cell at a rate proportional to the partial pressure of oxygen. The oxygen reacts in the cell and produces a voltage proportional to the concentration of oxygen. The voltage is measured by the Model GX-2003's circuitry, converted to a measurement of gas concentration, and displayed on the LCD.
