Oxygen

ZR202 is an integrated-type zirconia analyzer that combines the ZR402 remote analyzer and ZR22 detector in a single smart probe. It measures oxygen or moisture in situ. Because it reduces the need for pipe, cable and conduit, installation cost falls; it is useful for combustion air control at boilers and incineration plants.

ZR202 features

  • Local LCD and interface operated with infrared keys; settings are made without opening the cover.
  • Field-replaceable zirconia cell and heater assembly.
  • Integrated automatic calibration option; a separate ZR20H automatic calibration unit is also available.
  • HART for configuration and diagnostics; DD file and DTM available.
  • Explosive atmosphere versions are offered for ATEX, FM, CSA, IECEx and KOSHA.

Choosing ZR202

The manufacturer positions this instrument as low-cost and reconfigurable; a field-replaceable cell extends its life. If a separate detector and converter are wanted, the ZR22G and ZR802G separate system is selected.

Because the zirconia cell works heated, warm-up time and the reference air supply arrangement are planned together for initial commissioning. The stack connection flange and probe length are determined according to the duct's wall thickness and gas flow.

Tetra clarifies Ex requirements and automatic calibration needs at the start of the project. Maintenance steps such as probe mounting, test gas connection and supply of cell and heater spare parts are carried out in Türkiye.
