Overview
The TGH-STC U-shaped total copper water quality online automatic monitoring instrument adopts dimethyl spectrophotometric method. The mixture of water sample and strong oxidizing agent digestion solution is heated to 120 ℃. All forms of copper in the water sample are oxidized by the strong oxidizing agent under high temperature and high pressure conditions to form divalent copper ions. Then, reducing agent and masking agent are added, and finally, a color developing agent is added to form a yellow complex. Within the measurement range, the degree of color change is proportional to the copper concentration in the water sample. The analyzer detects this color change and converts it into the total copper value for output. The measurement method used by the instrument complies with HJ 486 Determination of Copper in Water Quality -2,9-dimethyl-1,10-phenanthroline spectrophotometric method.

The measurement method used by the instrument complies with HJ 486 Determination of Copper in Water Quality -2,9-dimethyl-1,10-phenanthroline spectrophotometric method.
Performance characteristics:
1. Select valve components: Choose reagent sampling timing, flexible and diverse channels, with advantages such as minimum volume, easy maintenance, and long service life.
2. Visual photoelectric system: Through the visual photoelectric system, precise measurement of reagents is achieved, overcoming quantitative errors caused by wear of peristaltic pump tubes.
3. Micro metering component: With precise quantification of trace reagents, it reduces the amount of reagents used.
4. Sample injection component: Peristaltic pump negative pressure suction, an air buffer zone is set between the reagent and the pump tube to avoid corrosion of the pump tube; At the same time, it makes the mixing of reagents more concise and flexible.
5. It has functions such as automatic range switching, automatic standard sample verification, and waste liquid separation.
6. Reagent tube: Imported modified PTFE transparent hose with a diameter greater than 1.5mm is used to reduce the probability of particle blockage in water samples.
Technical Specifications:
Application fields:
Applied to the measurement of total copper content in wastewater and surface water. Mainly used for water quality monitoring of pollution sources, industrial production process water, industrial and municipal sewage treatment, etc.
