Zirconia direct oxygen oxygen analyzer

DEVICE TYPE: ZKME direct sampling zirconia oxygen analyzer

Instruments made on the basis of this technology allow analyzing the oxygen concentration at ppm level.

Zirconia technology is based on the fact that when a certain temperature is reached, zirconium dioxide can play the role of a solid electrolyte, passing oxygen ions through itself, while zirconium atoms remain in the nodes of the crystal lattice.
