Purpose:
The application of vacuum box negative pressure method to collect gaseous samples can be used to collect various gases, including smoke, odorous gases, etc., especially suitable for sampling volatile organic compounds.
Adopting standards:
GB/T 14675-1993 "Determination of Odor in Air Quality - Three point Comparative Stinky Bag Method"
GBT 14678-93 "Air quality - Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide - Gas chromatographic method"
HJ604-2017 "Determination of Total Hydrocarbons, Methane and Non Methane Total Hydrocarbons in Environmental Air - Direct Injection Gas Chromatography Method (Draft)"
Main features:
1. Use vacuum negative pressure method to collect gaseous samples without contact with the sampler, achieving zero cross contamination sampling.
2. Multiple sampling methods to meet the needs of various sampling controls.
3. Real time pressure monitoring, automatic protection when the airbag is fully loaded.
4. The whole machine is produced by mold, which is beautiful, lightweight, and easy to carry.
5. The sampler is equipped with a high-performance lithium battery, which does not require AC power sampling.
6. Equipped with automatic cleaning function for airbags, no need to plug or unplug the airbag connecting tube.
7. Large screen Chinese display, human-machine dialogue, easy operation, and convenient use.
8. Specially developed sampling pump with long lifespan, high reliability, and graded control of sampling speed.
