                      1. PERFORMANCE
                      1) Measuring range :1-10 ppm 0.2-2.0 ppm
                      Number of pump strokes 1(100ml) 4(400ml)
                      2) Sampling time :1.5 minutes/1 pump stroke
                      3) Detectable limit :0.1 ppm(400ml)
                      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 :Pale orange→Blueish purple
                      2. RELATIVE STANDARD DEVIATION
                      RSD-low:10% RSD-mid.:10% RSD-high:10%
                      3. CHEMICAL REACTION
                      By reacting with an Oxidizer, Hydrogen chloride is produced and PH indicator is discoloured.
