The AII GPR-1800 oxygen analyzer is designed for use in demanding process environments where the low detection limit of industrial oxygen sensors can be utilized. The GPR-1800 is simple to use as well as easy and cost-effective to maintain thanks to the use of maintenance-free galvanic oxygen sensors. The optional liquid drain manifold protects and extends the sensor's life span in processes where entrained liquids may be present in the sample gas. There is a modular sample system available to suit most applications.
