产品简介：
Features 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, and, a stainless steel integral bypass sample system that enables the analyzer to come online at low PPM levels in minutes.
