Datasheet GPR-12-333-MH Datasheet GPR-12-333-M Datasheet GPR-12-333-H Datasheet
GPR-12-333 PPM O2 sensor is ideal for measuring oxygen 0-10 PPM in a gas mixture
GPR-1600
GPR-1200
GPR-1100
GPR-18
GPR-1800 Series
GPR-1500 Series
This innovative sensor design carries over many of the features of the traditional galvanic oxygen sensor but poses much higher sensitivity, stability and high signal to noise ratio with 24 months operating life thus offerring effective analyzer solution for measuring low levels PPM oxygen analysis.
