3rd Floor, Building 2, Medical Equipment Industrial Park, Daxue Road, High tech Zone, Heze City, Shandong Province

product overview
The GL-208GL high chlorine COD digester follows the Chinese environmental protection industry standard - determination of chemical oxygen demand for high chlorine wastewater - chlorine gas calibration method. The chemical solution preparation, operation, and COD calculation of the instrument are fully in accordance with HJ/T70-2001.

Product characteristics

1. The wavy strip heating wire of the heating plate is a new imported alloy material with a long service life.

2. Microcrystalline panels are capable of withstanding high temperatures up to 800 ℃, with uniform heating on the surface and fast heating and cooling speeds.

3. The heating plate is made of high-temperature resistant and heat-insulating ceramic fiber material, which has low panel heat loss and uniform thermal conductivity.

3. The microcrystalline panel is flat, smooth, and easy to clean. If the surface is contaminated, wipe it dry with a cloth.

4. The glass burr reflux tube has a good digestion reflux effect to ensure the accuracy of sample digestion results.

5. Dual screen digital display digestion time: temperature (between 165 ℃ -330 ℃) and timing can be set at any time.

6. After digestion is complete, the heating will automatically stop and the fan will continue to work for 120 minutes to assist in cooling the sample. It can be left unattended.
