Wide - Range Oxygen Sensor KGD - ZS - 321
Product Introduction
The KGD - ZS - 321 oxygen sensor is a five - wire planar wide - range oxygen sensor. There is no need for a regulating resistor on its connector. This type of sensor does not require a reference air sample. Instead, it uses the reference pump current as a fixed reference source to compare and calculate the oxygen content of the measured gas.
