1. PERFORMANCE
1) Measuring range :1-10 ppm 0.5-5 ppm
Number of pump strokes 1/2(50ml) 1(100ml)
2) Sampling time :1 minute/1 pump stroke
3) Detectable limit :0.2 ppm(100ml)
4) Shelf life :2 years
5) Operating temperature :0~40℃
6) Reading :Direct reading from the scale calibrated by Methyl mercaptan at 1 pump stroke
