Application Range
Standard Measuring Range: 0.01 to 0.4 ppm / 0.5 to 6 ppm
Number of Strokes n: see tube1) / 5
Time for Measurement: approx. 20 to 30 min /approx. 1 min
Standard: ± 20 to 25 %
Color Change: pale gray -› grey-brown
Ambient Operating Conditions
Temperature: 10 to 30 °C
Absolute Humidity: 1 to 20 mg H2O / L
Reaction Principle
N2H4 + Silver Salt -> grey-brown reaction product
Cross Sensitivity
1.1-Dimethylhydrazin and Monomethylhydrazine are shown with the same sensitivity (Standard Deviation ± 50 %) 5 ppm Ammonia at 100 strokes result in a measurement of approx. 0.01 ppm Hydrazine. At 5 strokes, Ammonia will also not be shown in high concentrations.
