summary:

Phosphorus is a key element in water eutrophication. In order to protect water quality and control hazards, total phosphorus has been included as a monitoring item in water environment testing.

Total phosphorus includesDissolved in waterSuspendedOrganic phosphorus andInorganic phosphorus, therefore the unfiltered water sample will be digested.Digestion is the process of converting various forms of phosphorus in water intoMethod for soluble inorganic phosphates. There are many methods for digestion, and users can choose according to the regulations. The total phosphorus detector can measure the content of inorganic phosphates in the dissolved aqueous solution.

Principle of the detector:
This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved.

Technical indicators:
1. Measurement range: 0-1.5mg/L
2. Power supply voltage: 220V
3. Resolution: 0.01mg/L
4. Repeatability: 3%
5. Linear error: ± (5% FS+1 word)
