Fenceline Monitoring System (FMS)

A durable, field-deployable solution engineered for continuous measurement of low levels of ethylene oxide with reliable results.

Equipped with an on-board Data Acquisition System (DAS), it integrates rapid, sensitive concentration data with high-frequency meteorological information for precise source attribution. Its modular sampling design supports both real-time data collection and longer-duration canister sampling. Featuring a mobile form factor, robust environmental controls, automated calibration, QA/QC processes, and cellular connectivity, the fenceline monitoring system is optimized for continuous, long-term operation in field conditions.
