                      7) Reading :Direct reading from the scale calibrated by 1 pump stroke
                      8) Colour change :White→Red
                      2. RELATIVE STANDARD DEVIATION
                      RSD-low:15% RSD-mid.:10% RSD-high:10%
                      3. CHEMICAL REACTION
                      Carbon tetrachloride is decomposed and Phosgene is produced. By reacting with this Phosgene,
                      4- (p-Nitrobenzyl)-phridine and Benzylaniline, dyestuff is produced.

                      (NOTE)
                      When the concentration is below 1 ppm, 2 pump strokes can be used to determine the lower concentration.
                      Following formula is available for the actual concentration.
                      Actual concentration=1/2×Temperature corrected value
                      6.CAUTION
                      When high concentration gas(over the full scale)is sampled, the indicator will be discoloured from pale yellow
                      to dark blue. If extremely high concentration gas is sampled, the detecting reagent may be faded and it is not
                      possible to distinguish with original colour.
