◆ The negative pressure passive sampling method is used to collect odor samples and other toxic and harmful gas samples. The collected gas samples enter the air bag directly from the sampling tube. The gas pipeline is made of polytetrafluoroethylene material to ensure that the samples are not adsorbed and avoid sample pollution.

◆ Built-in large flow sampling pump, fast sampling speed, strong ability to overcome load

◆ The vacuum box is made of stainless steel, which is sturdy and durable, with good sealing performance, and can form a negative pressure of 50kPa

◆ With four-speed speed regulation sampling function, it can meet the sampling requirements of pollutants in different working conditions

◆ It can detect the sampling air bag pressure, and automatically stop the sampling function when it exceeds the air bag pressure setting value.

◆ Gas sampling tube equipped with PTFE inner tube, which can be used for exhaust gas sampling from fixed pollution sources

◆ Built-in high-performance lithium battery for sampling without AC power

◆ Suitable for multi-specification sampling air bags from 1L to 10L
