1. Product introduction

QC-1S single gas path atmospheric sampler is an instrument for sampling a harmful gas in the air. It is suitable for the collection of various harmful gases in the air in environmental monitoring, health and epidemic prevention, occupational disease prevention, industrial and mining harmful gas collection, room environment measurement, college teaching, research and other units. The instrument is completed by two air pumps alone. It can collect samples of two different harmful gases at the same time, and can also collect balance samples and two samples at different times. It has the advantages of small size, light weight, simple operation, accurate timing, convenient use, large suction negative pressure, needle valve mechanical adjustment for regulating valve, fine adjustment scale and good stability. 's praise.

Executive standard: Q/0213 QJC013-2020 "Dual-channel atmospheric sampling"

2. Product parameters
