Brief introduction

The RB-890 microcomputer BOD5 analyzer uses a sensitive pressure sensor instead of mercury column and utilizes the air pressure difference method for biochemical oxygen demand measurement. It can accurately provide measurement results comparable to chemical dilution methods, directly read BOD values, and has the advantages of clear biochemical reaction curves and easy use and maintenance. It is an ideal tool for job analysis. It can be applied to environmental monitoring, petrochemical, medical and health, teaching and research departments to monitor water quality.

Microcomputer BOD5 analyzerUsing a simple sample dilution method makes 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 sixteen BOD bottles, connect the bottles to the pressure sensor of the microprocessor control device, select a suitable range from the four ranges, and the BOD testing device can complete the subsequent tests. 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.
