1. PERFORMANCE
1) Measuring range ：10-500 ppm
Number of pump strokes 1(100ml)
2) Sampling time ：1.5 minutes/1 pump stroke
3) Detectable limit ：1 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

2. RELATIVE STANDARD DEVIATION
RSD-low：15％ RSD-mid.：15％ RSD-high：10％
3. CHEMICAL REACTION
By decomposing with an Oxidizer, chlorine is produced. Yellowish Orthoquinone is produced by reacting
between this Chlorine and o-Toulidine.
