The O₂mation, model AV550G, averaging oxygen analyzer was designed with a focus on practical performance. In the spirit of the zirconia sensor "remaining life" diagnostic, Yokogawa introduces predictive calibration dates, cell asymmetry alarms and detector validation features.

Yokogawa's Zirconia oxygen detector systems offer a variety of calibration units for quick, easy control of calibration gases giving the user simple, accurate calibration.

The accumulation of fly-ash on the zirconia cell affects its ability to measure oxygen concentration. Flyash and its constituents can reduce the life of the zirconia cell and affect the cells response time to changes in gas concentration. Yokogawa's large surface area sintered metal filters are designed to keep particulate and ash off the measurement cell.

The IAC-24 is an ultra compact device that mounts directly onto the ZR22G or ZR202G zirconia detector. It is used to calibrate a single detector. The unique mounting configuration is designed to minimize installation time, wire pulls and tubing runs that are typical with auto calibration.

The OX400 is a highly accurate and reliable low-concentration zirconia oxygen analyzer that is capable of measuring a wide range of concentrations, from 0-10 ppm up to 0-100 vol%O₂.

The WZ-H cables supplied by Yokogawa Corporation of America are compatible with all Yokogawa ZR22, ZR402, and AV550G models. The purpose of these cables is to transmit the signal from the sensor/detector to the analyzer. Additionally, the cabling provides for electrical input to the heater assembly within the detector for cell temperature control.

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 EXAxt ZR202 transmitter / detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ humidity measurement. 

Accurate, repeatable measurement of humidity is mandatory for processes that use vapor as a heat source to facilitate drying. The drying process can consume significant amounts of fuel in order to operate the dryers. Therefore, proper control can reduce operating expenses and optimize the process as well. The EXAxt ZR402 analyzer features the industry's latest technological advances such as, easy-to-read, simple-to-use, LCD touch screen operation; real-time trend graphing of process variables; two user configurable analog outputs; and, three user configurable measurement parameters. .
