7 reasons why you need to measure CO2 inside of buildings


The TIM10 continuously shows carbon dioxide, temperature and relative humidity levels so you can monitor the quality of air in your home, office or indoor greenhouse. Just plug it in – the TIM10 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

Note that the battery is for time-of-day backup only! You must plug the TIM10 into the wall to use the unit.
