The Hach HQ430D Multi-Meter is an advanced BOD meter designed for water quality experts to take the guesswork out of measurements. The HQD BOD meter connects with smart Intellical electrodes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The HQD Laboratory Meter is designed to withstand years of continuous lab use. HQD meters feature a simple user interface that does not require manuals or training to operate, ensuring ease of use and efficiency in your water quality testing.
The Intellical LBOD101 is the latest embodiment of Hach’s patented Luminescent Dissolved Oxygen (LDO) technology. This digital, luminescent dissolved oxygen (LDO) sensor features a replaceable, integrated stirring system. The LBOD101 measures dissolved oxygen for BOD (Biochemical Oxygen Demand) determination in BOD bottles during BOD5 testing applications. It is used for both initial and final dissolved oxygen measurements.
