212 Low-Flow Vapor Monitoring System
The 212 Low-Flow Vapor Monitoring System (212 Low-Flow VMS) allows a trained field technician to collect a representative soil vapor sample for accurate quantification of volatile constituents in soil vapor. This data then can be paired with indoor air monitoring data to confidently assess the vapor intrusion pathway, make risk-based determinations, and withstand litigation scrutiny. When a technician uses our system in conjunction with our procedures and training videos, they will be able to successfully complete (1) shut-in testing, (2) pneumatic testing, (3) tracer testing, (4) stabilization verification, and (5) collection of a vapor sample within various type of media (when used 212's Soil Vapor Probe, Soil Vapor Probe Adapter, and Soil Vapor Sampling Tee).
First annual service included with purchase of the 212 Low-Flow VMS.
