Measurement range: 0.00 to 2.5 ppm (mg/L) NH3/NH4+
Resolution: 0.01 ppm
Accuracy @25°C/77°F: ±0.05 ppm ±5% of measured value
*For example, the water sample is 2ppm, the error is ±0.15 (2 ± 0.05 ±5% of 2) => the machine reads results ranging from 1.85 to 2.15 which is the correct allowable error of the machine
