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 including oxygen concentration, relative humidity, dew point, and moisture content.

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 flue gas measurement.

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 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 accumulation of flyash 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 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.
