产品简介：
Features the MS version of the proprietary Pico-Ion oxygen sensor capable of precisely measuring oxygen concentrations ranging from 10 PPB to 1000 PPM over a 24 month operating life with no periodic maintenance required, integral temperature control enhances stability, menu driven controls, and, a stainless steel integral bypass sample system that enables the analyzer to come online at low PPB levels in minutes.
