BOD LDO

Probe: Model LBOD10101

Safety Information

Read all labels and tags attached to the instrument. Personal injury or damage to the

instrument could occur if not observed.

Overview

Figure 1 on page 2 shows the LBOD10101 probe, a luminescent dissolved oxygen (LDO

)

sensor with an integrated stirring system. 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 cable.
