Intelligent vacuum box sampler

GHK-2033Intelligent vacuum box samplerEasy to operate, good sealing performance, passive sampling method for collecting various gases, especially suitable for sampling volatile organic compounds.

Implementation Standard

HJ/T55-2000 "Technical Guidelines for Monitoring Unorganized Emissions of Air Pollutants"

HJ732-2014 Sampling Bag Method for Volatile Organic Compounds in Fixed Pollution Source Exhaust Gas

HJ194-2017 Technical Specification for Manual Monitoring of Environmental Air Quality

Instrument Features

1. Collect gaseous samples using vacuum negative pressure method, with no contact between the sample and sampler, and zero cross contamination sampling.

2. The vacuum box body is transparent around and can monitor the real-time intake status of the airbag.

3. The flowmeter is installed in front of the air bag inlet, and the displayed flow rate and volume are the values of the gas flow rate and volume entering the air bag, with accurate measurement.

4. It has a constant flow sampling function: it can automatically adjust the sampling flow rate.

5. Sampling flow rate setting: It can automatically calculate the sampling flow rate value for 1 hour based on the set airbag volume, without the need for manual setting of the sampling flow rate value (can be manually set).

6. Sampling mode: You can choose immediate sampling, timed sampling, sampling mode, etc., and the program will automatically start and stop sampling.

After the sampling is completed, the gas path of the airbag will be automatically closed, and the gas inside the airbag will not leak or exchange with the outside gas.

After the sampling is completed, the negative pressure inside the vacuum box can be automatically released, making it easier to open the box and retrieve the airbag.

9. The program is suitable for sampling (1-10) L airbags (choose the size of the vacuum box as needed).

10. The sampler is equipped with a high-performance lithium battery and does not require AC power sampling.

11. Equipped with automatic cleaning function for airbags, the cleaning frequency can be manually set.

12. Adopting a touch color screen, the operation is simple and the sampling parameters are displayed in real-time.

13. Data storage and export: It can automatically store 10000 pieces of sampling data, which can be viewed, printed, and exported from a USB drive.
