AMETEK PI - Model 910 -Hot/Wet Multi-Gas Mass Flow CEM

The 910 performs all necessary flow management for sample and calibration gases, and provides probe and sample line temperature control, in addition to measurements mentioned above.

A full-featured continuous emissions monitoring (CEM) system, the 910 is ideal for measurements of stack emissions in the hydrocarbon processing industry.

HIGH-RESOLUTION UV TECHNOLOGY
With a dual-beam, multiple-wavelength configuration, the 910 delivers a resolution better than 0.02nm. The dual-beam design combines with a reference measurement to ensure low noise performance with minimal baseline and span drift.

NO INTERFERENCES FROM H₂O AND CO₂
Ultraviolet (UV) measurements do not suffer from water (H₂O) and carbon dioxide (CO₂) interference, as these species are transparent in the UV. This greatly simplifies sample handling and ensures a more accurate analysis.

FULLY EXTRACTIVE, HOT/WET ANALYSIS
The sample cell and all components in contact with the sample are heated above the dew points of all gases in the sample stream. This results in a simpler, more accurate calculation of gas concentrations.

The 910 is our complete CEM system for monitoring multiple pollutants in stack emissions on a mass rate basis. – Find out more.
