CO₂ measuring devices and CO₂ analyser – on the safe side with Testo
H2>
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.
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.

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. And so 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 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 CO₂?
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.
