Yokogawa Multi Channel Oxygen Analyzer System ZR22/AV550G

Zirconia Oxygen Probe/Sensor - ZR22
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.

Multi Channel Zirconia Oxygen Analyzer - AV550G
The O2mation, model AV550, averaging oxygen analyzer was designed with a focus on practical performance. Yokogawa has refined our expertise in the combustion oxygen business into this new and creative product. It is packed with features designed to minimize plant down time and technical support for the oxygen measurement. A multiple point oxygen measurement system may be required for situations when gas stratification in the flue duct affects combustion control. The AV550G averaging analyzer is ideal for combustion control in large utility boilers or various industrial furnaces.
Can accept inputs from up to eight ZR22 detectors
Sends both individual and averaged sensor outputs
Multipoint analyzer reduces installation and maintenance costs
Large 5.7-inch color LCD display shows various measurement, setup, calibration, and trend screens
Intuitive touchscreen is easy to read and simplifies setup and maintenance
Individual channel cards can be "hot swapped" 
4-20 mA standard outputs with HART or Foundation Fieldbus
