1. PERFORMANCE
1) Measuring range :1-20 ppm 0.5-10 ppm
Number of pump strokes 1(100ml) 2(200ml)
2) Sampling time :3 minutes/2 pump strokes
3) Detectable limit :0.01 ppm(200ml)
4) Shelf life :3 years
5) Operating temperature :0~40℃
6) Temperature compensation :Necessary(20-40℃)(See"TEMPERATURE CORRECTION TABLE")
7) Reading :Direct reading from the scale calibrated by 2 pump strokes
