1. PERFORMANCE
1) Measuring range :10-150 ppm
Number of pump strokes 1(100ml)
2) Sampling time :1.5 minutes/1 pump stroke
3) Detectable limit :6 ppm
4) Shelf life :1 year (Necessary to store in a refrigerated place ; 0~10℃)
5) Operating temperature :0~40℃
6) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading :Direct reading from the scale calibrated by 1 pump stroke
8) Colour change :White→Blueish purple
2. RELATIVE STANDARD DEVIATION
RSD-low:15% RSD-mid.:10% RSD-high:10%
3. CHEMICAL REACTION
By reacting with an Oxidizer, Hydrogen chloride is prodaced and PH indicator is discoloured.
C6H4CI2+PbO2+H2SO4→HCI
