Oxygen Analyzers

Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. These are used in a variety of measurement scenarios including, but not limited to, boiler trimming in power plants, furnace optimization in refinery and petrochemical applications, process safety in vent headers, and product quality in ethylene production.

Yokogawa offers a full range of product solutions including an industry leading zirconia oxygen probe series, as well as a line of cutting edge tunable diode laser spectrometers. 



In-Situ Gas Analyzer TDLS200

The TDLS200 is designed to make fast, accurate measurements of gases including oxygen (O2), carbon monoxide (CO), methane (CH4), moisture (H2O), carbon dioxide (CO2), ammonia (NH3), and hydrogen chloride (HCl). It is ideally suited for environments involving changing pressure or temperature.

Extractive O2 Analyzer TDLS220

The TDLS220 is specifically designed for accurate, reliable and low maintenance measurement of volume percent (vol%) oxygen (O2) for safety and process applications. It is a viable alternative to paramagnetic O2 analyzers.

Multi Channel Oxygen Analyzer System ZR22/AV550G

The AV550G multi channel oxygen analyzer system allows for measurements on up to 8 ZR22 probes simultaneously.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.

Single Channel Oxygen Analyzer System ZR22/ZR402

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.

Integral Oxygen Analyzer ZR202

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.

Calibration Units

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.

WZ-H Cables

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.

FLY-ASH Filter

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.

Low Concentration (ppm) Zirconia Oxygen Analyzer OX400

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.

IAC-24

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.
