Principle of Operation
This ATEX Certified Explosion Proof Oxygen Analyzer is a precision device designed to give you years of use. It has been
designed to incorporate several types of oxygen sensors enabling user’s to select an analysis range appropriate for their
application with the confidence of an ATEX certified analyzer system. Analysis ranges available with selected oxygen sensors:
GPR-18MS analyzes oxygen levels from 10 ppb (parts per billion) to 1,000 ppm (parts per million) and features the new “Pico-
Ion” Sensor Technology developed exclusively by Advanced Instruments Inc.
GPR-18 analyzes oxygen levels from 100 ppb to 1% (10,000 ppm) and features the advanced galvanic type ppm oxygen sensor.
GPR-28 analyzes oxygen levels from 0.05% (500 ppm) to 95% and features the advanced galvanic type percent oxygen sensor.
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.
