                      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→Red

                      3. CHEMICAL REACTION
                      By reacting with Nitro-benzyl pyridine, urea derivative is produced.
                      This urea derivative reacts with Benzyl aniline and dyestuff is produced.
