ZHK2640 Portable Soil (Gas) VOCs Comprehensive Sampling and Detection Instrument

This system is a portable soil (gas) VOCs compre-hensive sampling and detection instrument. The device includes a gas detection main unit and a complete gas sampling system. It can simultaneous-ly complete the drilling and sampling (soil gas samples) for different types of soil, and is capable of conducting initial screening of soil on-site (for parameters such as O₂, CO₂, H₂S, CH₄, TVOC, etc.).

This system allows for repetitive sampling of soil gas and enables the investigation of soil remediation efficiency, as well as the analysis of the composition of permanent gases in the soil. Additionally, it can perform preliminary measurements of VOCs content in the soil. This is a comprehensive soil sampling and detection system that can meet the diverse needs of different customers.

Gas Detection Main Unit

The detection main unit is equipped with a high-load pump, allowing for deep-distance sampling while simultaneously accommodating multiple gas detection modules (O₂, CO₂, H₂S, CH₄, TVOCs). It provides real-time display of CO₂ concentration variation curves,records data for various gas parameters in real time, enables data export, and allows the user to connect to a five-parameter meteorological instrument.

Stratified Sampling Soil Gas Probe

Equipped with a standard sampling head and a stratified sampling device, this probe features nylon and expandable rubber inflatable sealing cones suitable for different soil textures. Its unique stratified sampling device allows for the collection of soil gas from any soil layer within two meters.
