The TIM12 continuously shows carbon dioxide, temperature and relative humidity levels so you can monitor the quality of air in your home, office or classroom. Just plug it in – the TIM12 turns on instantly, is self-calibrating, and is designed to last for years.

Unlike chemical gas sensors that last for months and must be replaced, non-dispersive infrared diffusion sensors (NDIR) provide the following benefits:

  • Sensitive & accurate – information you can act on
  • Self-calibrating – no need to send the monitor in for recalibration
  • No moving parts – nothing to break or wear out
  • Does not lose accuracy in heat or cold
  • Able to store for long time periods – does not lose value over time
  • No over-exposure or negative memory effects
