AII portable oxygen analysers with ATEX certification

The portable galvanic electrochemical oxygen analyser range from Advanced Instruments Inc (AII) now has ATEX approval for use in atmospheres containing acetylene and/or hydrogen. The certified instruments include the GPR-1000, GPR-1100 and GPR-2000 portable range and the GPR-1200 premium portable analyser, which are used to measure oxygen to ensure product quality or avoid potentially explosive atmospheres by detecting leaks.

Using AII’s galvanic oxygen sensors, the portable analysers are simple to use with low maintenance. The sensors have a life between 24 and 32 months, and replacing them is quick and easy to do.

The portables have an innovative design which is said to eliminate the waiting time between measurements, providing an instant purge and a fast response to changes in oxygen levels. The instruments also feature a sample bypass system that isolates the sensors from high concentrations of air and allows a quick recovery from an upset. They are convenient to use in the field, with a long battery life of up to 30 days on a single charge.
