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
