Multi parameter water quality online monitoring instrument is a new type of multi parameter, integrated water quality online automatic monitoring instrument. The monitoring factors mainly include more than ten parameters such as pH, conductivity, dissolved oxygen, turbidity, temperature, residual chlorine, COD, permanganate index, ammonia nitrogen, total phosphorus, total nitrogen, chlorophyll, blue-green algae, flow rate, and flow rate. This multi parameter water quality online automatic monitoring instrument adopts a modular design, which can realize the monitoring function of any combination of multiple factors; Adopting visual operation, the operation is simple.
Heating a mixture of water sample, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as a catalyst can more effectively oxidize linear fatty compounds), and concentrated sulfuric acid to 170 ℃, the color of the organic matter in the dichromate ion oxidation solution will change. The analyzer detects this color change and converts it into COD value for output. The amount of dichromate ions consumed is equivalent to the amount of oxidizable organic matter.
Measurement factor:
PH、 Conductivity, dissolved oxygen, turbidity, temperature, residual chlorine, COD, permanganate index, ammonia nitrogen, total phosphorus, total nitrogen, chlorophyll, blue-green algae, flow rate, flow rate.
Maintenance cycle: usually once a month, about 30 minutes each time
Output: RS485
Display operation: Equipped with a color LCD touch screen
Data storage: can store measurement data for 3 years, data can be stored cyclically
Data export: Measurement values can be imported into a USB drive through a USB port and saved
Environmental requirements: recommended temperature range of 5-40 ℃; Humidity ≤ 90% (non condensing)
Power supply: AC220 ± 10% V, 50 ± 10% Hz.
Power consumption: 350W (excluding water pump)
Other: Data will not be lost in the event of a power outage or alarm, and the instrument will automatically drain any residual liquid from the system and return to standby mode.
