ZR402G/ZR22G Separate type Zirconia Oxygen Analyzer

The ZR402G zirconia oxygen analyzer features a touch screen LCD with excellent operability for settings, calibrations, and trend graph viewing. The probe uses a highly reliable zirconia sensor and a field-replaceable heater assembly.

The applications range from energy-consuming industries, such as iron and steel, electric power, and oil and petrochemical, to various combustion facilities, such as incinerators and small- and medium-sized boilers.

ZR202G Integrated type Zirconia Oxygen Analyzer

The ZR202G zirconia oxygen analyzer features an integrated probe and converter and does not require a sampling system. The probe can be inserted directly into a stack or furnace to measure the oxygen concentration of the stack gas.

The probe uses a highly reliable zirconia sensor and a field-replaceable heater assembly. The converter features infrared switches, allowing a user to operate the instrument without opening the cover in the field.

ZR22S/ZR202S Direct In-Situ Flameproof Zirconia Oxygen Analyzer

The ZR22S explosionproof zirconia oxygen probe is used together with a ZR402G non-explosionproof converter installed in a non-hazardous area. The probe can be inserted directly into a stack or furnace to measure the oxygen concentration of the stack gas.

The ZR202S explosionproof integrated type zirconia oxygen analyzer has both a probe and a converter, and does not require a sampling system.
The probe uses a highly reliable zirconia sensor and a field-replaceable heater assembly. The converter features infrared switches, allowing the user to operate the instrument without opening the cover in the field.

AV550G Zirconia Oxygen Averaging Converter

The AV550G Averaging Converter can accept inputs from up to eight zirconia oxygen detectors, reducing installation and maintenance costs. It sends output signals for individual and multiple (averaged) oxygen concentrations and can be used for combustion control.

The AV550G features a large 5.7-inch touch screen LCD with excellent operability for settings, calibrations, and trend graph viewing. The AV550G is ideal for combustion control in large utility boilers and various types of industrial furnaces.

OX400 Low Concentration Zorconia Oxyger Analyzer

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.
A proprietary new thin-film deposition technology was used in the zirconia sensor that creates a molecular bond between the zirconia element and the platinum layer. This prevents separation, enables a reduction in sensor size and ensures a high-speed response and long life.
The OX400 can be used to control and monitor various semiconductor applications, and to control environment, air leakage into inert gas, and other processes.

MG8G Paramagnetic Oxygen Analyzer (General-purpose Type)

The MG8G paramagnetic oxygen analyzer is a highly sensitive measurement instrument with excellent operability and reliability and measures the oxygen concentration of flammable gas mixtures. The sensor has a totally new architecture with a magnetic proportional flow rate system whose development was based on our long and field-proven experience.

A clean auxiliary gas (N2), not process gas, flows past the detection unit sensor. Therefore, a stabilized output that is not influenced by contamination from process or other corrosive gases can be obtained for long periods.

With no moving parts, the instrument is highly quake and shock resistant. The interference-gas compensation function ensures accurate measurement even in gases that exhibit a magnetic susceptibility, such as flammable gases.

MG8E Paramagnetic Oxygen Analyzers (Flameproof Type)

The MG8E paramagnetic oxygen analyzer is a highly sensitive measurement instrument with excellent operability and reliability and measures the oxygen concentration of flammable gas mixtures. The analyzer is of flameproof construction and the sensor has a totally new architecture with a magnetic proportional flow rate system whose development was based on our long and field-proven experience.

A clean auxiliary gas (N2), not process gas, flows past the detection unit sensor. Therefore, a stabilized output that is not influenced by contamination from process or other corrosive gases can be obtained for long periods.

With no moving parts, the instrument is highly quake and shock resistant. The interference-gas compensation function ensures accurate measurement even in gases that exhibit a magnetic susceptibility, such as flammable gases. Highly stable indications at near the zero point make the MG8E suitable for low-concentration measurements such as in safety control.

OX100 Current Limit Type Oxygen Analyzer (General Purpose Type)

The OX100 is a current limit type oxygen analyzer that is ideal for monitoring the oxygen concentration of ambient gases in production processes for semiconductors and electronic components, such as globe boxes, and for monitoring oxygen deficiency in clean rooms. It provides highly stable and accurate measurements for long periods, is easy to operate, and has a compact design, which make it suitable for integration into systems.

A measuring range between 0 and 1000 ppm or between 0.1 and 25% can be manually selected. A dedicated sampling unit is available for measurements where the sample gas contains a small amount of organic gases.

OX102 Enhanced Oxygen Analyzer

The OX102 is a current limit type oxygen analyzer that is ideal for monitoring the oxygen concentration of ambient gases in production processes for semiconductors and electronic components, such as globe boxes, and at nitrogen reflow furnaces. It provides highly stable and accurate measurements for long periods, is easy to operate, and has a compact design, which make it suitable for integration into systems.

The measuring range can be switched automatically, remotely, or manually to 0 to 100 ppm, 0 to 1000 ppm, 0 to 10000 ppm, or 0 to 25%. A dedicated sampling unit is available for measurements where the sample gas contains a small amount of organic gases.
