IIApplication of vacuum gas sampling box equipment:
The use of negative pressure outside the airbag method to collect gas samples can be used to collect various gases, including smoke and odorous gases, especially suitable for sampling volatile organic compounds and VOCs.
IIIProduct parameters:
Gas sampling bag
Type A: 1-4L Type B: 1-8L Type C: 10L
4Product features:
1. Gas samples are collected using negative pressure in a vacuum box. The vacuum pump inside the gas collector is used to extract the air from the vacuum box, causing the pressure outside the gas sample bag to be lower than the pressure inside the sample bag. As a result, the collected gas enters the gas sample bag. The advantage is that the sample gas is isolated from the collector and does not come into contact, which can effectively prevent the sample from being contaminated
2. Fast sampling speed and high efficiency. When cleaning and replacing residual gas in the airbag, there is no need to plug or unplug the airbag connecting tube. By controlling the "reversing button" on the collector, the residual gas in the airbag can be replaced in a clean air environment
3. The gas path uses chemically inert materials to ensure that the collected gaseous samples are not contaminated or adsorbed
4. Built in high-performance lithium battery, supporting long-term sampling;
5. Convenient to carry and easy to operate.
6. Optional sampling gun with dust filtering function, used for collecting exhaust gas in pipelines
