HD2071i typeVacuum box airbag samplerIt uses the airbag method to collect volatile organic compounds (VOCs) from fixed pollution source exhaust gas and ambient air, as well as other samplers suitable for collecting toxic and harmful gases using the airbag method. The principle is that the airbag passively collects external gas when the vacuum box is under negative pressure. The sample enters directly without passing through the sampling pumpEntering the airbag, there is no pollution to the sample, and it can be used for collecting waste gas in fields such as environmental protection, hygiene, labor, security inspection, military, scientific research, education, etc.

Product Features

1．Vacuum box airbag samplerCollect gaseous samples, isolate the injection gas path from the extraction gas path without contact, and achieve zero cross contamination sampling;

2．The host and sampling box are designed in an integrated manner for easy portability;

3．Equipped with a dedicated telescopic sampling tube with dust filtering function, used for collecting exhaust gas in the pipeline;

4．Adopting a high flow sampling pump, the sampling speed is fast and the load capacity is strong;

5．Can be continuousCollect 1L per hour;

6．Using dual air pumps for sampling, supporting high flow and fast sampling（3-speed, maximum 2.5L/min) and small flow precise sampling (8-100ml/min).

7．Equipped with automatic cleaning function for airbags, there is no need to plug or unplug the airbag connection tube, and the cleaning frequency and sampling mode can be set;

8．Real time monitoring of pressure inside the vacuum box, automatic stop of sampling when the airbag is fully filled;

9．After the sampling is completed, the negative pressure inside the vacuum box is automatically released, making it convenient to open the vacuum box;

10．Applicable toAirbags with specifications ranging from 1L to 10L;

11．Built in large capacity lithium battery, supporting long-term sampling;

12．2.8-inch color touch screen, making operation more convenient and efficient.;

13．Historical sampling data can be queried and stored10000 sets of sampled data;

14．Using Bluetooth printing technology, wirelessly print sampling data without the need to copy data, convenient and fast (optional).
