Atmospheric comprehensive samplerMain features:

1. Large screen LCD display, microcomputer simultaneously controls atmospheric sampling and particulate matter sampling, integrating atmospheric and particulate matter sampling, one click sampling humanized design, with memory function, no need to reset parameters when starting up;

2. It has the advantages of small size, light weight, low noise, high intelligence, stable flow rate, and reliable operation. The sampling bottle and drying bottle are designed with built-in structures, with good temperature control and light avoidance;

3. Intelligent digital setting of sampling flow rate (operating conditions), sampling time, sampling volume (standard conditions) and other parameters; Calibrate values such as flow rate, temperature, pressure, time, etc;

4. Dual gas path and dual pump sampling, with two continuously adjustable flow rates;

5. Good air path sealing

The absorption bottle is connected to the gas path using an absorption bottle sealing joint, which is easy to use and reliable in sealing;

6. Automatic heating function

Using imported sensors, when the temperature is below15Automatically heated at ℃, above25Stop heating at ℃, temperature control accuracy:（20±5）℃；

7. Automatic protection function of sampling gas path

The anti backflow filter dryer in the sampling gas path structure can not only dry the gas in the filtered gas path, but also prevent the absorption liquid from backflow into the lower gas path, playing a role in protecting the flowmeter and pumping power;

8. Equipped with gas path color recognition function, convenient for users to identify gas paths;

9. Adopting imported high-efficiency and low-noise brushless fans, with a long service life, it can run for 20000 hours with low noise.

10. Overload automatic protection: During the sampling process, if the sampling flow rate is less than or greater than the set sampling flow rate, the instrument will automatically stop

Machine protection.

11. Power outage protection function: During the sampling process, if there is a power outage, the sampling data can be automatically saved and sampling can continue after a power call.

12*The drying cylinder with a three in one design of drying, filtering, and anti backflow suction can efficiently dry moisture, filter dust, and prevent backflow suction, achieving long-term operation without cleaning.
