EPM.300 Series Diluting Stack Sampler Thermo Scientific™

Prepare a sample from the stack with the Thermo Scientific™ EPM.300 Series Diluting Stack Sampler, which performs the four critical functions of sample delivery, course filtering, fine filtering, and sample dilution. The Thermo Scientific™ dilution probes are proven performers with low maintenance requirements in the field and a long life on the stack.

Model PRO3000 Full Extractive Probe Thermo Scientific™

Conduct wet- or dry-basis measurements with the Thermo Scientific™ Model PRO3000 Full Extractive Probe. Housed in a NEMA 4X enclosure to protect it from harsh environments, this probe is highly durable and easily mountable to the stack or duct.

PRO2001WHP Dilution Extractive Probe Thermo Scientific™

Conduct wet-basis measurements with the Thermo Scientific™ PRO2001WHP Dilution Extractive Probe, an external, low-flow probe designed to handle the toughest environments.

Housed in a NEMA 4X enclosure to protect from harsh environments, this probe is highly durable and easily mountable to the stack or duct. It is capable of extracting a sample from a stack or duct, through a heated probe barrel, and filtering out the sub-micron particles using a heated filter to dilute the sample for transport down the umbilical for analysis.

PRO903 Dilution Probe Thermo Scientific™

Handle the toughest stack environments with Thermo Scientific™ PRO903 Low Flow Dilution Probe, a modular, external, low flow dilution probe designed for dry-basis measurement that offers significant advantages over typical in-stack dilution probes.

Model PRO902C Low Flow Dilution Probe Thermo Scientific™

Handle the toughest environments with the Thermo Scientific™ Model PRO902C Low Flow Dilution Probe, which offers significant advantages over typical in-stack dilution probes. The dilution extractive technology in combination with the thermo-electric cooler provides accurate and concise readings available in both terms of concentration and mass-emission rates.

Model 200LS and 200LD Dilution Probe Controller Thermo Scientific™

Meet U.S. EPA requirements for stack monitoring with high measurement sensitivity, fast response times and robust operation in harsh environments.  The Thermo Scientific™ Model 200LS and Thermo Scientific™ Model 200LD dilution probe controllers offers easy integration with other Thermo Scientific™ iSeries gas analyzers for a complete CEMS solution.
