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.

Back to top
The PRO903 dilution probe chills the sample stream via a thermoelectric collar to remove the moisture in the sample. Once the sample has been conditioned, dry air dilution lowers the sample dew point. The conditioned sample can then be transported via an unheated umbilical to the gas analyzer.

Key Features:

  • Automatic purge at probe filter and barrel to prevent PLC failure
  • Optional O2 measurement upgrade
  • Heated sample line not required
  • Filter and sample chiller temperatures controlled and alarmed by rack-mounted PID controllers

Recommended for:

  • Utility boilers
  • Pulp mills
  • Waste-to-energy facilities
  • Incinerators
  • Turbines
  • Refineries
  • Petro-chemical plants
  • Gas plants
  • Cogeneration facilities
