Analytical Industries (AII)

Oxygen measurement is the whole business of Analytical Industries Inc., usually shortened to AII. Founded in 1990 and based in Pomona, USA, the company makes its own galvanic electrochemical oxygen sensors and builds analyzers around them. Seven Star LLC lists the AII GPR-1500 trace ppm oxygen transmitter and supplies AII analyzers and replacement sensors to gas plants and nitrogen users in Oman on inquiry.

AII GPR oxygen transmitters and analyzers

The manufacturer presents the GPR-1500 and GPR-2500 together as its trace (ppm) and percent oxygen transmitters. Ranges are user-configurable, and the transmitters are offered in safe-area and hazardous-area configurations. Around them sit industrial, portable and hazardous-area oxygen analyzers and H2S analyzers. The sensor program covers trace ppm, percent and 100 percent purity sensors, plus replacement sensors for existing industrial instruments.

Ordering AII analyzers and sensors: what we need

Send the analyzer model and serial number, the sensor part number printed on the cell, the background gas, the expected oxygen level, sample pressure and whether acid gases such as CO2 or H2S are present. State the area classification as well. GCC natural gas users should mention the H2S content of the stream.
