CO meter
The carbon dioxide (CO2) content of the air is an indicator of the indoor air quality – assuming that human respiration constitutes the main emission source for the CO2.
With Testo you are always on the safe side.
Measuring instruments with CO2 sensors such as a CO2 analyzer, enable you to reliably control this important value: because, as the air quality falls (increasing CO2 content in the air), performance also falls. A CO2 analyzer or measuring device from Testo has a range of advantages.

5 tips for efficient CO2 measurement!
It is very quick to sum up which CO2 measuring instrument it is possible to use for reliable recording of exhaust gas: each of the numerous Testo models meets the high requirements made by professional users all over the world. As to ensure you actually achieve maximum measurement precision with your CO₂ measuring instrument, simply take these 5 small but important tips into consideration:
Choose the right measuring instrument: Do you need a CO2 meter for continuous data logging, or do you take measurements sporadically at various locations? Depending on your requirements, a stationary CO2 data logger or a portable CO2 or indoor climate meter—such as the testo 400—would be ideal.
Consider ambient conditions: Both fine dust and condensation affect the optical path and, consequently, the measurement results.
Do not breathe on the probe: Your breath is saturated with CO2 and must not be directed toward the probe. Simply use a tripod and stand a short distance away.
Measure at head height: When taking measurements in the workplace, determine the CO2 level at the head height of the people working there.
Perform a routine check if CO2 levels are high: Elevated CO2 concentrations may indicate that the ventilation system is not set correctly. A quick check is always a good idea.
What is CO?
When people breathe out, they release colorless and odorless carbon dioxide – a gaseous combination of carbon and oxygen which is harmful or deadly at a high concentration:
If the CO2 concentration in the air we breathe rises above 150,000 ppm, unconsciousness occurs.
The CO2 limit value in offices is 1,000 ppm.
The optimum value is 400 ppm.
