The indicator for indoor air quality is the carbon dioxide (CO 2 ) content of the air - assuming that human breathing is the main source of emissions for the CO 2 .
Measuring devices with a CO 2 sensor enable you to reliably monitor this important value: as air quality decreases (increasing CO 2 content in the air), performance also decreases.
Easy, accurate CO2 measurement.
Robust, tried and tested instruments.
Ideal for monitoring and optimizing indoor air.
CO2 measuring instruments with unbeatable price-performance ratio.
It's easy to say which CO2 measuring device can be used to reliably record exhaust gases: Each of the numerous Testo models meets the high demands of professional users all over the world. And to ensure that you actually achieve the maximum measurement precision with your CO₂ meter, simply follow these 5 small but important tips:
Das passende Messgerät auswählen: Benötigen Sie ein CO2 Messgerät für die kontinuierliche Datenerfassung oder messen Sie eher sporadisch an unterschiedlichen Orten? Je nach Anforderung ist ein stationärer CO2 Datenlogger für Sie ideal oder ein tragbares CO2 bzw. Klimamessgerät wie das testo 400
Auf die Umgebungsbedingungen achten: Sowohl feiner Staub als auch Betauung beeinflussen die optische Strecke und damit die Messergebnisse.
Nicht auf den Fühler atmen: Ihre Atemluft ist mit CO2 gesättigt und darf nicht in Richtung des Fühlers strömen. Nutzen Sie einfach ein Stativ und stellen Sie sich etwas abseits.
Auf Kopfhöhe messen: Bestimmen Sie bei Messungen am Arbeitsplatz den CO2 Wert auf Kopfhöhe der dort arbeitenden Personen.
Routinecheck bei erhöhtem CO2: Liegt eine erhöhte CO2 Konzentration vor, kann es daran liegen, dass das Lüftungssystem nicht korrekt eingestellt ist. Ein kurzer Check ist immer gut.
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.
What would you like to measure? At Testo, you will find a measuring instrument which meets the highest demands for every VAC parameter: temperature, humidity, flow, pressure, measuring instruments for refrigeration systems, data loggers and lots more.
Easily monitor the air quality in rooms where lots of people are present via WiFi. No matter whether the areas are open-plan offices, museums or nursery schools: a Testo IAQ data logger will give you the ideal support.
Testo provides you with the ideal set-up for controlling industrial and environmental noise. Choose the sound level meter which suits your tasks.
Testo's high-precision lux meters help you to ensure optimum light conditions.
Whether contactless rpm measurement via a reflective marker and light beam or contact measurement via a measuring wheel: find the best rpm measuring instrument for use in air conditioning technology or in other fields of application.
Would you like to set your ventilation and air conditioning system or control the indoor air quality? Then why not measure all the VAC parameters with just one instrument. Which one? Here you will find the appropriate multifunction measuring instruments for your applications.
Ensure an efficient heating system with high-precision flue gas analysis. These flue gas analysers make sure you can work efficiently. You can record highly dangerous carbon monoxide as an individual parameter at lightning speed with a special CO measuring instrument.
The testo Smart App guides you quickly and easily through measurements on refrigeration, air conditioning and heating systems.
