Vacuum box airbag sampler

Product Overview:

Vacuum 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 the airbag directly without passing through the sampling pump, which is non polluting to the sample and can be used for collecting exhaust gas.

Execution standard:

HJ 732-2014 Sampling Gas Bag Method for Volatile Organic Compounds in Fixed Pollution Source Exhaust Gas

HJ 38-2017 Determination of Total Hydrocarbons, Methane, and Non Methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources - Direct Injection Gas Chromatography Method

HJ 604-2017 Determination of Total Hydrocarbons, Methane, and Non Methane in Environmental Air - Direct Injection Gas Chromatography Method

HJ 1262-2022 Determination of Odor in Environmental Air and Waste Gas - Three point Comparative Stinky Bag Method

HJ/T 55-2000 Technical Guidelines for Monitoring Unorganized Emissions of Air Pollutants

Product Features:

1. Gas samples are collected using negative pressure in a vacuum box, with the injection and extraction gas paths isolated and not in contact, achieving 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 to collect exhaust gas in the pipeline;

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

5．Vacuum box airbag samplerCan collect 1L continuously for 1 hour;

6. Use dual air pumps for sampling, supporting high flow rapid sampling (3 gears, maximum 2.5L/min) and low flow precise sampling (8-100ml/min).

7. It has an automatic cleaning function for airbags, without the need to plug or unplug the airbag connection tube. 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;

After the sampling is completed, the negative pressure inside the vacuum box will automatically release, making it convenient to open the vacuum box;

10. Suitable for airbags 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 can store 10000 sets of sampling data;

14. Using Bluetooth printing technology, wirelessly print sampling data without copying data, convenient and fast (optional).
