Overview

The national standard COD reflux digestion instrument adopts a 7-inch intelligent LCD touch screen design, with simple and convenient one click operation, and automatically completes the digestion and cooling process. No need for manual supervision. Microcrystalline panel heating, fast heating rate, uniform heating. Equipped with a dedicated condenser bracket for safer operation.

Product Details

HW-1000 typeNational standard COD reflux digestion instrumentIt is developed based on the national standard method HJ828-2017 for the determination of chemical oxygen demand (potassium dichromate method). It adopts a 7-inch intelligent LCD touch screen design, with simple and convenient one click operation, and automatically completes the digestion and cooling process. No need for manual supervision. Microcrystalline panel heating, fast heating rate, uniform heating. Equipped with a dedicated condenser bracket for safer operation.

Widely used for COD determination in industries such as environmental protection, medical care, hygiene, food, tap water, papermaking, pharmaceuticals, sewage treatment, printing and dyeing, petrochemicals, metallurgy, and scientific research institutions.

Execution standard:

HJ 828-2017 Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method


Product Advantages:

1. National standard COD reflux digestion instrumentUsing 10 digestion wells, acid, alkali, and corrosion resistant, with even heating.

2. 10 digestion wells can be individually controlled, and each one can be individually set for heating time and temperature.

3. Use a 250ml conical flask as the digestion container specified by the national standard to facilitate titration and mixing. After digestion, titration can be carried out directly without the need for pipetting, which is time-saving and efficient, and complies with the national standard.

4. 7-inch color touch screen, intuitive display of channel parameters, real-time observation of heating temperature and countdown.

5. Adopting a dual condensation method of air cooling and water cooling, with 4 high air volume axial fans for heat dissipation, to ensure the condensation effect.

6. Two high flow axial fans are installed at the bottom to cool down the digestion bottle and heating plate after digestion is completed, accelerate the experimental progress, avoid high-temperature burns, and ensure experimental safety.

7. The digestion program adopts PID temperature control to ensure the digestion temperature.

8. Implement one click digestion, the digestion process is automatically completed, and the power is automatically turned off to end the heating after digestion.

9. The reflux condenser tube has a horn opening, which prevents the addition of reagents from flowing out and facilitates cleaning after digestion.
