The QCOD-2H portable COD speed measuring instrument

This product is to use sealed catalysis digestion, and then were measured by colorimetric method, special oxidation agent containing potassium dichromate isadded with a certain volume in strong acid solution, and in the special catalyst at 165 ℃ constant temperature digestion of water for 10 minutes, the six valence chromium dichromate in organic compounds in water samples was reduced to trivalent determination ofchromium, trivalent chromium at the wavelength of 610mm, and then converted to the concentration of COD.

QCOD-2H this product has the following main features:

1 use the cold light, monochromatic light as the light source, optical stability is excellent, can not be interfered by various light.

Automatic control of digestion temperature 2 PID, high precision of temperature control.

3 double liquid crystal display, simple operation.

4 high temperature digestion and colorimetric (including computer) is separated in two parts, so that the temperature minimum to optical effects.

5 a resolution of 12 water samples of each batch ofsamples, determination of time only 20 minutes.

6 memory 255 with time tag measurement data.

7 data power-off will not be lost.
