Electrochemical analyzers and sensors for oxygen and hydrogen sulphide

Analytical Industries Inc electrochemical oxygen sensors and analyzers, H2S analyzers and associated sample conditioning systems are exclusively sold and supported internationally through Michell Instruments as well as other Process Sensing Technology Group companies.
AII’s oxygen analyzers are based on the galvanic measurement principle and offer robust, high-precision measurements meeting the highest quality standards.

The range of products is comprehensive with over 25 analyzer models and more than 175 sensors for applications in industries such as air separation, steel production and pharmaceutical processing.
With the proprietary Pico-Ion oxygen sensor, the PI2-UHP-50/100 PPB O2 analyzer offers a lower detection limit of less than 0.1ppb, which is ideal for quality control of ultra-high purity inert gases in the semi-conductor industry. The portable oxygen analyzers such as the GPR 2000 and GPR1200 measure oxygen from % level to trace levels as low as parts per billion in both general purpose and hazardous areas.
For applications in natural gas, refineries and petrochemical industries, the GPR-1800 Trace oxygen analyzer and GPR-7500 range of H2S analyzers have approvals from both ATEX and UL for use in hazardous areas around the world.
