Product features:

The MX-890 BOD analyzer is a new type of instrument that uses the air pressure difference method for biochemical oxygen demand determination, and can accurately provide information comparable to chemical dilution methodsThe measurement results have the characteristics of intuitive readings, clear biochemical reaction curves, and easy use and maintenance, making it an ideal tool for job analysis. Ke GuangWidely used for monitoring water quality in departments such as environmental protection monitoring, petrochemicals, healthcare, teaching and research.

MX-890 BODDetailed information of the measuring instrument:
BOD testing device that can run unattended
The standard five-day dilution method requires tedious sample preparation and operation to obtain reliable results, and a microcomputer controlled BOD testing device and simplified BOD method are used,

You can quickly and accurately complete important tests. The entire device operation process can be unattended.
Thanks to effective and easy use
The testing device uses a simple sample dilution method, making BOD measurement easy without the need for remote control facilities. The operator only needs to simply add the measured sample and BOD nutrient buffer to 8 BOD bottles, connect the bottles to the pressure sensor of the microprocessor control device, and select a suitable one from the four ranges

The range and BOD testing device can complete the subsequent testing. After the sample temperature stabilizes, the device begins to read the BOD value and store it in the instrument's memory. It is recorded every 15 minutes and can be tested for a period of 5 or 10 days.

MX-890typeBODMeter

Characteristics of BOD testing device
1. Automatic shutdown
2. Mercury free device ensures accurate BOD measurement
3. Automatically collect and store data
4. Convenient button interface
5. Simply press the button to print the display image directly
6. Input and output through USB interface
7. Independent channel characteristics can measure 8 sample parameters separately
8. LCD graphic display continuously updates BOD test results and status
9. The electromagnetic stirrer continuously stirs to ensure that oxygen is replenished to the sample
10. The sample is easy to dilute and can measure high range BOD effectively and completely. During the BOD measurement process, the BOD testing device is sensitive to pressure

The probe continuously monitors the changes in oxygen consumption of the sample, and the BODmg/L concentration measured directly by the instrument does not need to be calculated or extrapolated. A pressure probe is used to avoid

Use mercury pressure gauge and dissolved oxygen measurement.
The automatic stirring device continuously stirs to enhance oxygen transfer, and the mechanical device does not have a motor, reducing maintenance and ensuring accurate results. Oxidation of organic compounds

The generated CO2 is absorbed by lithium hydroxide contained in the bottle cap. Continuous graphical display of BOD testing device electronically storing measurement data and updating results.

In testingAt any time during the trial, the rate of BOD change can be detected on the LCD display screen. It can store 480 points of data during measurement.

You can easily see the BOD curve of any sample bottle. Select the sample number with the button to display the start date and current BOD value

Pre testing scope and real-time time. Moving the cursor along the BOD curve will display the sample number, BOD value, and measurement duration.
