Product Description

Emerson's Rosemount CT4400 is the world's first purpose-built hybrid Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) process gas analyzer designed to enhance performance and reduce costs specifically in NOx measurement and continuous emissions monitoring applications. Optimized for cold/dry applications running at ambient pressure, the CT4400 rack-mount analyzer allows easy integration into existing plant infrastructure without costly consumables or maintenance.

Features

  • Measures up to seven application-specific gas components simultaneously with enhanced dynamic range from sub ppm to percent levels
  • Ideal for environmental monitoring applications measuring standard components, such as NO, NO2, SO2, CO, CO2, and O2
  • Compatible with existing plant infrastructure to minimize disruption or cost when replacing legacy analyzers
  • Rosemount™ QCL/TDL technology with patented laser chirp technique enables detection of individual gas species, free from cross-interference effects of other gas in the stream
  • Sub-second measurements with high-sensitivity and high-accuracy monitoring ensure compliance with regulatory requirements
  • No complex sample treatment or consumables reduce costs and improve plant efficiency
  • Rugged, interchangeable modular configuration holds up to four laser modules and delivers outstanding reliability and measurement stability
  • Inherently stable spectroscopic technique reduces calibration needs and delivers reliable performance
