Ammonia (NH4+)

Reagents for rapid manual analysis of the ammonium content in water in the concentration range 0–10 mg/l NH4+. The individual values 0.1 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. The colour comparison device for easy concentration determination can be ordered separately or as part of a set with the reagents. 1 set of reagents (1xA, 1xB, 1xC) Number of analyses: approx. 70 Measuring time: approx. 4 minutes Also available from us: Complete colour comparison set Testoval Ammonium: Order no.: 410680 Replacement colour comparison device Testoval Ammonium: Order no.: 410682

Color comparison kit for the rapid manual analysis of ammonium content in water in the concentration range 0-10 mg/l NH4+. The individual values ... 0.1 mg/l, 0.5 mg/l 1 mg/l 2.5 mg/l 5 mg/l 10 mg/l ... can be read by visual color comparison.  By diluting the water sample in a ratio of 1:10 with distilled water, the measuring range can be extended to 10 times the concentration. In addition to the two reagents a color comparison device for easy determination of concentration is included in the supply. Number of analysis: approx. 70 Measuring time: approx. 4 minutes Also available from us: 1 set of reagents for approx. 70 analyses: Order no. 410681 Replacement colour comparison device for ammonium: Order no. 410682
