desktop CO2 & RH/T monitor

CO2Meter tim-10-desktop_1024x1024The TIM12 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 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

To use the data logging feature:

  • Record data to unit’s built-in memory
  • Install the free (included) software on your PC
  • Plug the included USB cable into your PC
  • Start the software to view or save data

Note that the battery is for time-of-day backup only! You must plug the TIM12 into the wall to use the unit or to read logged data on a PC.
