Product Description

Microporous Filter, Filter,PE/PA Microporous Filter Tubes,Filter Recycling Technology

The vacuum sampler collects air samples in a pre-vacuumed sampling canister, which can be used for both instantaneous and averaged samples. Instantaneous samples are collected simply by opening the valve of the sampling canister and using the vacuum inside the canister to draw the air sample into the canister for a short period of time (usually less than 5 seconds). The sample collected in this way represents the surrounding air pollution conditions at the moment the valve is opened. The collection of averaged samples (also known as mixed samples) is a bit more complicated. When the valve is opened for sampling, it is necessary to control the flow rate of the gas sample into the sampling canister, so that the gas is sampled at the same rate throughout the sampling period.

Usage of vacuum sampler
Used to collect gas samples, such as non-methane total hydrocarbons, malodorous gases and so on.
It can be used in the fields of gas analysis, detection and monitoring.
Features of vacuum sampler
Vacuum pump pumping, can quickly collect gas samples.
Small size and light weight, easy to carry and move.
Simple and convenient operation, easy to use and maintain.
