Application Range
Standard Measuring Range: 10 to 200 / 1 to 20 ppm
Number of Strokes n: 1 / 10
Time for Measurement: approx. 1 min / approx. 10 min
Standard Deviation: ± 15 %
Color Change: white -> brown
Ambient Operating Conditions
Temperature: 2 to 40°C
Absolute Humidity: max 40 mg H2O / L
Reaction Principle
H2S + Cu2 -> CuS + 2H+
Cross Sensitivity
500 ppm hydrochloric acid, 500 ppm sulfur dioxide, 500 ppm ammonia or 100 ppm arsine do not interfere with the reading. Methyl mercaptan and
ethyl mercaptan change the entire indicating layer to a pale yellow. When mixed with hydrogen sulfide, the reading is extended by approx. 30%.
