AII

Electrochemical oxygen sensors and gas analyzers

About the manufacturer

Analytical Industries Inc. (AII) is a US manufacturer specialising in electrochemical oxygen sensors and gas analyzers. The company started in California and for more than three decades has developed proprietary oxygen-measurement technologies for demanding industrial, medical and breathing-safety applications.

AII’s core expertise is electrochemical oxygen sensing and instrumentation for trace and high-purity O2 measurement. The company develops both sensors for OEM integration and complete analyzers for process control. AII now operates as a DwyerOmega brand while retaining its specialist focus on gas measurement.

The company’s solutions are designed for applications in which measurement quality directly affects process quality, user safety or compliance with technological requirements. The portfolio covers sensors for different concentration ranges, operating conditions and integration methods.

Applications

AII sensors and analyzers are used wherever reliable oxygen monitoring is required, from industrial processes to breathing systems.

Industrial process control – oxygen monitoring in process gases and technological installations.
Specialty and technical gases – purity control and trace O2 measurement.
Medical equipment – oxygen sensors for respiratory and medical devices.
Diving – monitoring breathing-gas composition and air quality.
Electronics and semiconductor manufacturing – monitoring process atmospheres.
Food and packaging – monitoring modified atmospheres.
Laboratory and analytical equipment – integration with measuring systems and data loggers.

AII products available from Maritex

Maritex offers specialist AII electrochemical oxygen sensors for precise O2 concentration monitoring in industrial and measurement applications.

Available product groups include:

Electrochemical oxygen sensors.
Sensors for low and trace O2 concentrations.
Sensors for integration with gas analyzers.
Sensors for process-control systems and measuring instruments.

One example in the range is the GPR-12-333-M electrochemical oxygen sensor, designed for measurement up to 10,000 ppm O2. Selection should consider the measuring range, response time, connection type, temperature and pressure conditions and the composition of the gas in which the sensor will operate.
