Hydrocarbon Vapor Sensor

Applications

• Monitoring bioventing, vapor extraction, and air-sparging systems
• Long-term monitoring of natural attenuation
• Monitoring of ex-situ bioremediation systems such as biopiles and landfarms

Features/Installation

• Install directly in soil or hang in existing monitoring well with screened interval in vadose zone.
• Proven Adsistor® sensor technology as used in UST leak detection
• Third party approvals from UL, FM, CSA, and US EPA
• Hydrocarbon logger has low-range settings to allow for increased sensitivity as hydrocarbon levels decrease
• Sensor is not cross sensitive to CO₂, H₂O, H₂S, CH₄, or O₂
• Equipped with sampling port for calibration, simultaneous pressure monitoring, and soil gas sampling
• Requires no maintenance or external power source. Calibrate on installation and annually thereafter.
