PHA-100 – Portable Hydrocarbon Analyzer

PetroSense sensors are non-specific detectors for TPH, semi-volatile hydrocarbons (e.g., diesel fuel, heating fuels, etc.), trichloroethylene/perchloroethylene and many other related compounds. The detection capability of these sensors is unaffected by high humidity, or by naturally occurring methane.

The PHA-100 portable hydrocarbon analyzer is designed to meet field monitoring requirements. In the analytical mode, it gives fast and accurate quantitative data for total petroleum hydrocarbons in water and vapor. The data correlates very well with lab gas chromatographic analysis. In the screening mode, it offers fast relative data on TPH contamination, tracking field gas chromatograph data for TPH, and responds strongly to BTEX components.
