Trace Oxygen Analyzer for Process Industries
GPR-1800 IS, GPR-1800 AIS
The GPR-1800 series of intrinsically safe trace oxygen analyzers are designed for use in demanding process environments where the low detection limit down the AII’s industrial oxygen sensors can be well utilized. Typical for Analytical Industries gas analyzers, they are simple to use as well as easy and cost-effective to maintain thanks to the use of their maintenance-free galvanic oxygen sensors. The innovative liquid drain manifold, which is available as an option, protects and extends the sensor's life span in processes where liquids may be present in the sample gas.
