The BOS FLEXSENSE II is a versatile optical oxygen sensor. 1/2” Male NPT connections fit toflow cell installations where frequent access to the sensor is required. Oxygen measurement is accomplished through a replaceable luminophore sensing cap. A removable fiber optic wand is used to transmit the optical signal to/from the window. The BOS FLEXSENSE is rated for pressures up to 1,200 PSIG making it well suited for wet, untreated H2S laden natural gas and offshore produced water-floods.
