CO2 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 analyser, 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 analyser 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 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. So 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 appropriate measuring instrument:
Do you need a CO₂ measuring device for continuous data recording or do you tend to carry out measurements sporadically at different locations instead? Depending on the requirement, either a stationary CO₂ data logger or a portable CO₂ or air velocity & IAQ measuring instrument, like the testo 400 is ideal for you.Take the ambient conditions into account:
Both fine dust and condensation influence the optical path and therefore the measurement results.Do not breathe on the probe:
The air you breathe is saturated with CO₂ and must not flow in the direction of the probe. Simply use a stand and move a little to one side.Measure at head height:
For measurements at the workplace, determine the CO₂ value at the head height of the people working there.Routine check when the CO₂level is raised:
If there is a raised CO₂ concentration, it may be due to the ventilation system not being correctly set. A quick check is always a good idea.
What is CO 2 ?
When people breathe out, they release colourless and odourless 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.
