1. Product introduction

Juchuang QC-2A double gas path atmospheric sampler is an instrument for sampling one or two harmful gases in the air at the same time. It is suitable for the collection of various harmful gases in the air by 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.
