GPR-1900 SERIES PPM OXYGEN ANALYZER

Features a compact size that lends itself to being integrated into an existing system or custom factory built analyzer, an advanced galvanic trace PPM oxygen sensor capable of precisely measuring oxygen concentrations ranging from 100 PPB to 1% over a 24 month operating life with no periodic maintenance required, menu driven controls, two (2) field selectable alarm set points, and, a full range of analog outputs.
