Origin: USA, can directly replace some Japanese brands (thin tube) oxygen probes

Diameter: 0.84 inches

Oxygen probes utilize zirconia ceramic sensitive elements to measure oxygen content in various application environments.

ZrO2 is a typical ionic crystal. When doped with binary or trinary cubic symmetric oxides such as CaO, MgO, Y2O3, and other trivalent rare earth oxides, ZrO2 can become an oxygen fast ion conductor above 600°C, which is referred to as a solid electrolyte.
