Principle of Operation
The GPR-1200 MS portable oxygen analyzer incorporates a proprietary Pico-Ion oxygen sensor. The analyzer is
configured in a general purpose NEMA 4 rated enclosure and meets the intrinsic safety standards required for use
in Class 1, Division 1, Groups A, B, C, D hazardous areas. Two integral sampling pump options are available – one
that meets the intrinsic safety standards and a less expensive option for general purpose service.
Breakthrough Sensor Technology:
A breakthrough sensor technology measures the partial pressure of oxygen from less than 10 ppb to 1000 ppm
level in inert gases, gaseous hydrocarbons, helium, hydrogen and mixed gas streams. The “Pico-Ion” sensor design
and chemistry have been combined to produce a significant advancement in oxygen sensor technology.
