描述

The MAX-250B oxygen sensor is a galvanic cell type oxygen sensor. It is similar in operation to a conventional amperometric oxygen sensor (conductive positive/KOH electrolyte, KE series), but is more unique chemically. Because the sensor uses a weakly acidic electrolyte, the MAX-250B oxygen sensor is used in some applications such as radiation testing.
