The PRO902C External Low Flow Dilution Probe handles the toughest environments while offering significant advantages over typical in-stack dilution probes. The Low Flow Probe meets EPA requirements as defined in 40 CFR 75 and 40 CFR 60 for continuous emissions monitoring, using dilution extractive technology for dry basis measurement.
Product Detail
APPLICATIONS: Utility boilers, pulp mills, waste-to-energy facilities, incinerators, turbines, refineries, petrochemical plants, gas plants, and co-generation facilities where regulations or permits for these facilities are stated in terms of concentration (e.g., ppm) rather than mass emission rates (e.g., lbs/hr).
