Cost-effective portable trace oxygen analysers for cargo tank safety

09 October 2018

Analytical Industries’ range of trace oxygen analyzers, distributed by Michell Industries in the UK, France, Germany and Italy, makes routine spot checks for leak detection (air ingress) in storage tanks and other vessels quick and easy to do. 


With a battery life of up to 30 days on a single charge, they are ideal for field work. Using AII’s proprietary galvanic oxygen sensors, the portable analyzers are simple to use with low maintenance. The sensors have a service life between 24 and 32 months and are easily replaced.

The GPR-1100 portableis suitable for trace oxygen measurements from 0.1 ppm. The Quick-Connect gas fittings allow the user to protect the sensor by trapping a sample with low oxygen inside. Despite its small size, it’s tough and durable for demanding industrial applications. 
The GPR-1200 portable O2 analyzer utilises the same sensor technology and has an innovative design which virtually eliminates the waiting time between measurements and greatly increases the sensor life. The integrated bypass system isolates the sensor and allows the operator to set the flow ensuring the connecting pipework is flushed through before sampling takes place. 
Typical applications include spot checks of storage tanks and marine vessel holds as well as welding gas purity and nitrogen generators.
