ECOPROBE 5 is the ultimate solution for soil contamination survey. It combines advantages of Photoionisation detection (PID) and Infra-red spectroscopy (IR). This device replaces a number of separate analysers with one small, compact instrument. It provides the user with the in-situ measurement of organic contaminants with selective analysis of methane, group of common petroleum hydrocarbons, CO2, O2, NO2 and H2S.
