BODT-5N BOD is a new type of instrument for measuring biochemical oxygen demand by air pressure difference method. It can accurately provide the measurement results comparable to chemical dilution method. It has intuitive reading, biochemical reaction curve at a glance and convenient maintenance. , is the ideal tool for job analysis. It can be widely used in environmental monitoring, petrochemical, medical and health, teaching and research departments and other departments to monitor water quality.
BOD test device that can be left unattended. The standard five-day dilution method requires cumbersome sample preparation and operation to obtain reliable results. The microcomputer-controlled BOD test set and simplified BOD method allow you to quickly and accurately complete important tests. The entire equipment operation process can be left unattended.Thanks to effective and easy use. The test device uses a simple sample dilution method to make BOD measurements easy and does not require remote
control facilities. The operator simply adds the measured sample and BOD nutrient buffer to the sixteen BOD bottles, connects the bottle to the pressure sensor of the microprocessor control unit, selects a suitable range from the four ranges, BOD test The device can complete future tests. When the sample temperature stabilizes, the device begins to read the BOD value and stores it in the instrument’s memory, recording every 15 minutes, and optionally testing for 5 or 10 days. During the BOD measurement process, the sensitive pressure probe of the BOD test device continuously monitors the change of oxygen consumption of the sample. The BODmg/L concentration directly measured by the
instrument is not calculated or extrapolated, and the pressure probe is used to avoid the mercury pressure gauge and
dissolved oxygen determination. The automatic stirring device continuously agitates the transmission of enhanced oxygen, and the mechanical device has no motor, which reduces the maintenance amount and ensures accurate results. The CO2
produced by the oxidizing organic matter is absorbed by the lithium hydroxide contained in the cap.Continuous graphic display.
The BOD test set electronically stores measurement data and updates the results. The rate of BOD change can be detected on the LCD display at any time during the test. 480 points of data can be stored in the measurement. You can easily see the BOD curve of any vial. Use the button to select the sample number to display the start date and current BOD value, current test range and real time. Moving the cursor along the BOD curve displays the sample number, BOD value, and measurement duration.
When the analysis is complete, the computer downloads the stored data via the RS232 interface. You can also collect experimental data in real time using a computer.
The instrument consists of a visual large-screen liquid crystal display, a microprocessor, an amplifier, a BOD culture flask, and a biochemical incubator. The biochemical incubator and the BOD culture flask can be supplied separately.
