Intellical™ LBOD101 is the latest embodiment of Hach’s patented Luminescent Dissolved Oxygen (LDO) technology. The LBOD101 is a digital, luminescent dissolved oxygen (LDO) sensor with a replaceable, integrated stirring system. The LBOD101 measures the dissolved oxygen for BOD (Biochemical Oxygen Demand) determination in BOD bottles in BOD5 testing applications. The LBOD101 probe is used for initial and final dissolved oxygen measurements. The LBOD101 is fitted with an automatic pressure sensor module. The DO sensing cap comes with an iButton to track days in use and remind remaining life of the sensing cap element.
