                      Tube 13SB

                      1. PERFORMANCE
                      1) Measuring range :100-2000 ppm
                      Number of pump strokes 1(100ml)
                      2) Sampling time :1.5 minutes/1 pump stroke
                      3) Detectable limit :15 ppm
                      4) Shelf life :2 years
                      5) Operating temperature :0~40℃
                      6) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
                      7) Reading :Graduations printed on the tube are calibrated by Hexane at 1 pump stroke and
                      Heptane concentration is determined by using a conversion chart at 3 pump strokes.
                      8) Colour change :Orange→Yellowish green
                      2. RELATIVE STANDARD DEVIATION
                      RSD-low:10% RSD-mid.:10% RSD-high:5%
                      3. CHEMICAL REACTION
                      Chromium oxide is reduced.
                      CH3(CH2)5CH3+Cr6++H2SO4→Cr3+
