AMI Sensors

Through years of intensive research and development AMI’s is able to offer its patented electrochemical oxygen sensor that yields an extremely rapid response, high reliability, and longer product life. AMI has also perfected proprietary manufacturing techniques that resolve many of the common problems found in other electrochemical oxygen sensors.

AMI’s oxygen sensors provide an industry-leading resistance to H₂S, in concentrations up to 500 ppm. This breakthrough eliminates the need for a maintenance intensive H₂S scrubber for the sample gas.

Every trace and percent oxygen sensor manufactured in our Costa Mesa, California facility undergoes a battery of performance tests, including response times, noise, drift and linearity, across multiple temperature ranges, to insure they meet our strict quality standards.

Substituting a lesser oxygen sensor in your high-performance AMI oxygen analyzer will severely degrade the performance of your analyzer was well damage the analyzer and void the warranty.

The electrochemical sensors for AMI’s 3000RS and 3010BX trace H₂S analyzers are available in two different ranges to fit your application requirements. The low range is designed for applications up to 200ppm of H₂S while the high range can support installations up to 2000 ppm.

AMI’s H₂S sensors are constructed as a three electrode amperometric electrochemical cell. They generate a current that is linearly proportional to the volume of H₂S in the gas sample. AMI’s H₂S sensors and trace analyzers are precisely designed, configured and factory verified to work together and provide safe, fast and reliable measurements in harsh applications.

AMI’s zirconium oxide sensors are an extremely stable, have a very long service life, and are not affected by barometric or temperature changes. They are an excellent option for measuring percent levels of oxygen in inert atmospheres, such as the amount of oxygen in the air of an enclosed space. In this application AMI’s zirconium oxide sensor will last for many years and require minimal calibration. These sensors should not be used for measurement of oxygen in flammable gasses and are not designed for low ppm levels of oxygen.

Zirconium oxide sensors in AMI analyzers are not field replaceable. When the time comes for a new sensor in your analyzer this work can be quickly performed by our technicians at the AMI factory.
