Lambda T

CO2 gas monitor and controller for labs, green houses and growth chambers

A high accuracy CO2 monitor employing a novel twin wavelength, non-dispersive, infra-red, optical technique. This detection system ensures that the monitor is gas specific and maintains long-term calibration stability.

Features

  • Continuous CO2 monitoring
  • Reliable IRGA technology
  • Integral sample pump
  • IP54 rated for harsh environments
  • No costly consumables
  • Two configurable alarm relays
  • The Lambda T is a highly accurate CO2 monitor employing a novel twin wavelength infrared gas analyzer. This technology provides highly stable analysis, enabling the Lambda T to be used for unattended measurement and control of CO2 in conditions of elevated CO2 such as greenhouses,and growth chambers.

    The twin wavelength detection system means the Lambda T is very specific for CO2, with no cross sensitivity to other gases and highly stable, essential for long term measurements.
