Hac-100 standard cod digester adopts microcomputer technology to regularly control the heating electric furnace. The instrument is mainly composed of body, return pipe, fan and electric furnace plate. Microcomputer technology is used to control the heating of electric furnace plate and fan at fixed time. Multiple 250ml flat bottom triangular flasks or 10 straight flasks can be heated by reflux at the same time. Achieve the purpose of saving energy, reducing power load and improving efficiency.

The instrument adopts glass burr return pipe instead of spherical return pipe, and air cooling technology instead of tap water cooling, which can not only save water, standardize the instrument, but also improve the safety of the instrument. The chemical solution preparation, operation and COD calculation of the instrument fully comply with gb11914-89. The accuracy of COD water samples lower than 50mg / l can be improved by diluting titrant and oxidant, and COD water samples higher than 100mg / l can be determined by proportional dilution of water samples.

Product features

1. The number of two opposite spherical condensing bubbles protruding from the condensing pipe wall is increased to three, ensuring the improvement of condensing effect.

2. The COD automatic digestion reflux instrument is used in the south. Because the weather temperature is high and the sample is easy to volatilize, a volatilization cap is covered on the condenser pipe. The heating effect of the sample and the accuracy of the analysis are ensured.

3. From 5 samples to multiple samples, 250ml flat bottomed triangular flask is heated in two ways, with good bottom contact and uniform heating. It is convenient to operate and sample in two ways.

4. The quality and importance of electric furnace plate and electric furnace wire. The electric furnace plate does not deform when heated, and the electric furnace wire is not easy to break when heated. Good materials are selected.

5. Air cooling and water cooling replace the previous circulating water cooling. The power and position of the fan are very important. It is improved according to many years of operation experience. Domestic fans with excellent quality are selected with reliable quality.

6. Double fan convection cooling, which can be controlled independently.

7. The immortal steel heating pipe is used for heating, with fast and uniform heating speed and long service life.

After digestion, the instrument will automatically alarm and stop working. Water and electricity saving, small radiation and small space occupation.
