Modular External Low Flow Dilution Probe Dry Basis with Oxygen Analyzer

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 Details
