Testoval Phosphate Test, Refill Pack Reagents

Refill pack: 1 set of Testoval Phosphatest® (ortho-phosphate) reagents for rapid manual analysis of the phosphate content in water in the concentration range 0-10 mg/l P2O5. The individual values 0.25 mg/l, 0.5 mg/l, 1 mg/l, 2.5 mg/l, 5 mg/l and 10 mg/l can be read by optical colour comparison. By diluting the water sample with distilled water in a ratio of 1:10, the measuring range can be extended to 10 times the concentration. The reagents are supplied for approximately 180 analyses for easy concentration determination.
