1. Product introduction

The QC-2A dual gas path atmospheric sampler is an instrument for sampling one or two harmful gases in the air at the same time. Different gases can be collected according to the preparation of different solutions. Implementation standards: Q/0213 QJC013-2020 "Dual-channel Atmospheric Sampling", JJF1404-2013, JJG956-2013 Atmospheric Sampler Verification Regulations and other standards.

The instrument is suitable for environmental monitoring, health and epidemic prevention, occupational disease prevention, industrial and mining harmful gas collection, room environment measurement, college teaching, research and other units to collect various harmful gases in the air. 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.

2. Product Features

1. Large LCD screen, clear data, easy to operate.

2. Automatic locking function, effectively prevent misoperation.

3. In the setting interface, the font can be enlarged for easy operation.

4. Equipped with a pause function, which can be stopped and resumed at any time , and is equipped with an anti-suckback function.

5. Low battery reminder function. It can still be sampled when the battery is too low.

6. When the sampling is over, the screen backlight will automatically turn on and prompt.

7. Dual-channel design, can collect two kinds of gases or parallel samples, and can be controlled separately.

8. The display screen automatically adjusts the contrast and brightness, which is suitable for use in a variety of complex lighting environments.

9. The instrument is small in size, light in weight, easy to operate, accurate in timing, and has a large negative pressure for suction. The regulating valve is mechanically adjusted by a needle valve ( 304 stainless steel material ) , with fine adjustment scale and good stability .
