This instrument is a portable soil (gas) VOCs sampling and monitoring tester. The system includes a gas sampling system, a soil drilling and soil collection device. It can complete the hole opening and sampling of different soils at one time (soil, soil gas samples), and complete the preliminary screening of soil (O2, CO2, H2S, CH4, TVOCs and other concentration parameters) in the field. This system can not only realize repeated sampling of soil gas, but also realize the investigation of soil remediation efficiency, understand the composition of soil permanent gas, and preliminarily measure the content of VOCs in soil. It is a set of soil comprehensive sampling and testing system, which can meet the needs of different customers.
The gas detection host is equipped with a high load pump, which can realize deep distance sampling. At the same time, it can be equipped with multiple gas detection modules (O2, CO2, H2S, CH4, TVOCs) to display the variation curve of CO2 concentration, and users can connect the five meteorological parameters to record the gas parameters in real time and export the data.
Sampling soil gas probe is equipped with common sampling head and layered sampling device. For different texture soil, it is equipped with nylon and flexible rubber inflatable sealing cone. The unique layered sampling device can collect soil gas in any soil layer within two meters.
