1. Product introduction

QC-2S 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. 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 liquid crystal display, menu operation, computer timing, small size, light weight, convenient operation, accurate timing, large suction negative pressure, mechanical adjustment of the regulating valve by needle valve, fine adjustment scale, and good stability. Since it was put on the market, it has been favored by users.
