Product Description

 

 A mixture of water sample, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as a catalyst can oxidize linear aliphatic compounds more efficiently), and concentrated sulfuric acid heated to 165°C, the dichromate ion oxidation solution The color of organic matter will change, the analyzer detects the color change, and converts this change into COD value and outputs it. The amount of dichromate ions consumed corresponds to the amount of oxidizable organic matter.

 

 

 

Characteristics
The digestion and colorimetry of the instrument is completed in one body, the structure is simple and reliable, and the possibility of errors is reduced.
Adopt imported modified PTFE transparent hose, the diameter of which is greater than 1.5mm, which reduces the amount of water samples
Particle blockage probability.
It can automatically clean the sampling pipe to prevent the formation of algae or biofilm.
After abnormal reset and power failure, the instrument automatically discharges the residual reactants in the instrument and automatically returns to the working state.
Low failure rate, less maintenance and less reagent consumption.
Intelligent fault self-diagnosis function, alarm prompt, instrument management and maintenance are very convenient.
Using PLC and other control units to reduce environmental interference and equipment failures.
Using multi-channel valve, strong anti-corrosion performance, long service life, safe and reliable.

 

 

 

Application field
Chemical industry: medicine, chlor-alkali chemical, pigment and dyestuff, pulp and paper, intermediate, fertilizer, starch, taibai powder, pesticide, metallurgy, viscose, detergent and other industries;
Water treatment: air scrubber, boiler inlet water, cooling water, thermal power plant water; wastewater: electroplating wastewater, industrial wastewater, heavy metal precipitation.
