The air must be drawn into the probe to generate an electric potential only under vacuum conditions. The main functions of the zirconia probe are primarily three:

(1) Energy Conservation (2) Environmental Pollution Reduction (3) Extend Furnace Life

The ZO-300 Direct-Insert Zirconia Probe is suitable for boilers, kilns, oil refineries, chemical plants, power plants, etc., that require coal, oil, and other fuels for heating.

Burning furnace chamber and flue. This instrument accurately and rapidly reflects the instantaneous oxygen content during the combustion of the furnace chamber, enabling timely and effective control of the smoke.

　　Throttle plates, accelerator pedals, and air intake gates, etc., play a significant role in improving combustion thermal efficiency, conserving energy, and reducing pollution. ZO-300 Direct Insert

The flue where the zirconia probe is inserted must be under negative pressure, as the reference gas for the zirconia probe is air, which flows naturally.
