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 includes water-soluble, suspended, organic phosphorus, and inorganic phosphorus, therefore unfiltered water samples are digested. Digestion is the method of converting various forms of phosphorus in water into 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)
