Main features:

1. Atmospheric sampling has three distinct characteristics: light avoidance, insulation, and precise flow rate:

1.1 Inside the atmospheric insulation box, 2-8 absorption bottles can be placed in the dark;

1.2 The instrument has insulation function: when the temperature inside the insulation box is below 20 ℃, the sampler automatically starts the heating function;

1.3 Each gas path has an automatic measurement and control circuit composed of a suction power, flow sensor, etc., with precise flow measurement and control.

2. The sampling settings are flexible, and each gas path can independently set the sampling time, flow rate, and run separately.

3. There are five sampling modes for users to flexibly choose from: quantitative sampling, immediate sampling, timed sampling, interval sampling, and 24-hour sampling.

4. Able to digitally calibrate parameters such as temperature, pressure, flow rate, and time.

5. Automatic measurement and standard conversion: Automatically measure environmental temperature, atmospheric pressure, flow rate, pre gauge temperature, and pre gauge pressure, and automatically convert the sampled volume into standard condition volume and reference volume.

6. Overload protection: During the sampling process, if the sampling flow deviates from the set flow by more than ± 10% for 5 consecutive minutes, the instrument will automatically shut down for protection and give a prompt.

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

8. Air path protection: Transparent anti backflow suction drying bottles are connected in series in the air path to prevent moisture or absorbent from entering the air path and damaging the suction pump, sensor, and air path.

9. Imported brushless fans and brushless air pumps are used as the suction power for particulate matter and atmospheric sampling, with long service life and low noise.

10. The particle cutter, filter membrane clamp, and flowmeter are all patented technologies with independent intellectual property rights.

11. Data storage and export: Each gas path can store 100 (expandable) sampling data, which can be viewed, printed, and exported from a USB drive.

12. The sampler is easy and simple to fix on the triangular bracket (patented technology).

13. Rain and snow resistant design, mold production, high reliability, small size, and light weight.

14. High and low temperature resistance: It can work normally in an environment of (-30~50) ℃.

15. Equipped with a high-capacity built-in lithium battery, it can continuously sample for more than 8 hours when all functions are turned on; It can also be powered by AC power supply.
