Series 9000 - CO Monitor

Product Enquiry

Series 9000 cross stack infrared, in-situ carbon monoxide monitors provide high accuracy and reliability, coupled with straightforward installation and setup and is suitable for a wide range of industrial combustion efficiency monitoring applications. This carbon monoxide monitor is designed to provide the operator with a fast response measurement, essential to the efficient combustion control of any boiler system.

Product Range

Model 9100 Carbon Monoxide Monitor Model 9200 MkII High Performance Carbon Monoxide Monitor

The 9200 MkII has all the facilities of the 9100 with the addition of:

  • Clear stack, open path gas calibration
  • Automatic cell leak detection
  • 4 gas cell, TUV approved measurement technique
  • Automatic duct pressure correction

Background of Experience

LAND has been developing carbon monoxide monitors for over 20 years, the Series 9000 represents the fourth generation of products.

Cross-stack vs Extractive Analysers

Cross stack, infrared measurement, benefits from producing an average carbon monoxide reading over the entire duct or stack. They respond very quickly, unlike extractive analysers which are often too slow and inaccurate due to using a single sampling point and a long sample line.

On-Board diagnostics

The series 9000 carbon monoxide monitor features continuous self diagnostics and calibration checking - in addition to full modbus communication capability to a plant or boiler DCS.


  • Boiler Combustion Efficiency
  • Low NOx Burner Performance
  • Burner Performance Monitoring
  • Process Control
  • Precipitator Protection
  • Monitor Boiler Erosion

Simple installation and setup

The Series 9000 has a transmitter and receiver unit only - no additional interface or calibration boxes are required; All it requires is installation and mains power supplying. Setup, and in particular alignment could not be simpler - the transmitter has a signal strength indicator to achieve the best measurement performance.

The Model 9100 has the accuracy and repeatability of an environmental analyser and the simplicity and reliability of a combustion process monitor.
