Fosofrates are always present in water, even in minimal amounts. Only the increase in their concentration causes problems, m.in. Dispose of algae or sicn. Milwaukee MW12 meter allows you to measure the concentration of phosphates in both fresh and salt water with an accuracy of 0.01 ppm (from 0 to 2.5 ppm).
Range: 0.00 - 2.50 ppm
Resolution: 0.01 ppm
Accuracy: +/- 0.04 ppm +/- 4% @ 25 * C
Light source: LED @ 525 nm
Detector: Silicon Fotodiode
Measurement method: Adaptation of the standard method of water and waters measurement, 20 editing the ascorbic acid method. The reaction between phosphates and reagent causes a blue color in a test tube.
