  二、 Product features:

  1. According to the test needs, continuous and accurate oxygen supply, one bottle of electrolyte can supply oxygen for more than one year;

  2. Precise temperature control: water bath temperature control, temperature setting range 4-90 ℃, temperature regulation accuracy ± 0.1 ℃;

  3. Mutual verification of dual detection systems;

  4. The actual oxygen consumption of the sample was determined by charge movement;

  5. Direct measurement of carbon dioxide production by conductivity measurement;

  6. Channel number: each instrument includes 9 detection channels;

  三、Product principle:

  The actual biological oxygen consumption of the sample was measured by measuring the charge movement. The ratio of the actual oxygen consumption to the theoretical oxygen consumption was used to determine the biodegradability of the sample. The consumption of carbon dioxide was determined by the change of conductivity after absorption of carbon dioxide by sodium hydroxide solution. The biodegradability of the sample was determined by the ratio of actual production of carbon dioxide to theoretical production of carbon dioxide. In theory, the two kinds of test results verify each other, so as to ensure that the detection results are more accurate.
