异丙基溴 2-溴丙烷气体检测管 2-bromopropane (CH3)2CHBr 10-500ppm

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