Ventilation / Air Quality

• Measurement of air speed, temperature, humidity at the air vents
• Measurement of CO2 at the air vents (Wöhler FA 430 only)
• Detection of air leaks
• Integrated measurement of volume flow
• Direct measurement of volume flow at air vents in combination with the cone
• Measured data display and management in the Wohler FA 4xx App

The Wöhler IQ 300 CO2 meter is ideal for monitoring air quality in classrooms, waiting rooms, seminar rooms, etc.. It evaluates the air quality at any time based on measurement data. An important factor for monitoring indoor air quality is the CO2 content. Through breathing, people release moisture and CO2 into the indoor air and, if they are sick, also viruses. A high CO2 content in the air therefore indicates an urgent need for ventilation, because if this value is high, it can be assumed that the air is also polluted with other substances. Via a brightly traffic light LED as well as a clearly audible tone, the Wöhler IQ 300 warns when ventilation is required. The limit values for the warning functions are adjustable. If desired, users can also mute the warning tone, as the large display also shows clearly when the air quality becomes critical.

Carbon Monoxide Measurement Knowing the carbon monoxide measurement in the area of installation and maintenance of a gas boiler or heating system is extremely vital due to carbon monoxide being lethal at high concentrations in the ambient air. The Wöhler CM 220 carbon monoxide detector is a handy, easy to use device for carbon monoxide detection, offering outstanding accuracy and good operability. In particular, the device is suitable for checking carbon monoxide measurement during the installation of gas ovens, central heating systems, stoves, water boilers, etc., as well as for checking the air quality in areas such as underground garages and workplaces.

The Wöhler CDL 210 CO2 data logger and the Wöhler CDL 110 CO2 data monitor are CO2 measuring devices (colloquially also called CO2 traffic light) for continuous monitoring of the carbon dioxide concentration (in ppm) and other air quality factors. Determination of the indoor air quality through combination of measurement and identification of:

• The CO2-concentration
• The air temperature
• The air humidity

For CO2-monitoring of:

• Housing spaces (comfortableness, humidity problems, etc.)
• Conference rooms and lounges (e.g. schools)
