产品简介：
Features a compact size that lends itself to being integrated into an existing system or custom factory built analyzer, the MS version of the proprietary Pico-Ion oxygen sensor capable of precisely measuring oxygen concentrations ranging from from 10 PPB to 1000 PPM 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.
