The industry leading ZR22 in-situ type Zirconia detector provides dependable and accurate oxygen measurement. Available in lengths from 15 cm to 5.4 meters, the ZR22 can be used in process temperatures up to 700ºC (up to 1871ºC with our close-coupled extractive adapter ZR22P), and pressurized ducts up to 2.5 bar with the pressure compensating option.

The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process. The new probe's modular design incorporates a rebuildable heater and thermocouple assembly, the industry standard field replacable Yokogawa Zirconia cell, and removable reference and calibration lines to create an oxygen measurement product designed for simple, quick and low-cost field maintenance.
