The LBOD10101 probe is a luminescent dissolved oxygen (LDO
stirring system
(Figure
1). The LBOD10101 measures the dissolved oxygen for BOD
(Biochemical Oxygen Demand) determination in BOD bottles. The probe uses the
luminescent dissolved oxygen (LDO) technology (no membranes) and features a
replaceable self-stirring assembly and a 1.8 meter (5.91 ft) cable.

    Option Description Salinity Sets the salinity correction—Off (default), Manual. Correction Salinity lowers the solubility of dissolved oxygen in water. To correct for salinity in the sample, set salinity correction to manual and then enter the salinity value. Salinity Value Sets the salinity value—‰ (default: 35.0 ‰). When salinity correction is set to manual, sets the salinity value of the sample.
