Brief introduction

RB-300 air-cooled CODThe disintegrator isRB-100New generation upgraded product with instruments following international standards（The basic principles of ISO and GB standards ensure the digestion operation with reflux heating and micro boiling for 2 hours. The preparation and addition of reagent solutions are consistent with the GB method, ensuring reliable and accurate analysis results.

This oneAir cooled CODDigesterBy using microcomputer technology for timed control of far-infrared electric furnace plates, 8 digestion cone reflux devices can be heated simultaneously. To achieve the goals of energy conservation, reducing power load, and improving efficiency.

ThisAir cooled CODDigesterThe use of glass burr reflux pipes instead of spherical reflux pipes, and the use of air cooling technology instead of tap water cooling, can not only save water and standardize the instrument, but also improve the safety of instrument use.

The chemical solution preparation, operation, and COD calculation of the instrument shall comply with HJ 828-2017 (replacing GB11914-89)）, lower thanThe accuracy of COD water samples with a concentration of 50mg/L can be improved by diluting the titrant and oxidant, while COD water samples with a concentration higher than 700mg/L can be determined by diluting the water sample proportionally.

2、 Technical features

1High temperature resistant microcrystalline ceramic glass panel, with fast temperature rise and fall speed and uniform heating.

2After the digestion of the triangular flask is completed, it can be directly titrated for measurement, which is convenient to shake well and does not require transfer.

3Uniform heating and long service life

4.The digestion time can be set, and after digestion is complete, the instrument automatically stops heating and can be left unattended.

5.After the sample digestion is completed, the instrument fan continues to work to assist in cooling the sample.

6.Replace water cooling with air cooling,Saving electricity and water, improving efficiency, and enhancing the safety of instruments.
