CO2 monitor tfa dostmann AIRCO2NTROL UP 31.5010 — digital display, CO2, temperature, humidity

Portable CO2 monitor tfa dostmann AIRCO2NTROL UP 31.5010 is a compact indoor air quality instrument with a digital display that shows CO2 concentration, temperature and relative humidity. The unit is designed for tabletop or shelf placement and provides clear numeric readouts to help assess ventilation needs in homes, offices, classrooms and meeting rooms. The monitor enables easy observation of indoor air parameters that influence comfort and airborne transmission risk.

Advantages

This tfa dostmann CO2 monitor combines three measurements—CO2 concentration, air temperature and relative humidity—on a single digital display for quick assessment of indoor conditions. Its compact format supports portable use and placement on a desk or shelf without requiring permanent installation. Numeric readouts allow straightforward comparison with recommended CO2 thresholds to guide ventilation decisions. The device is suitable for routine checks and rapid identification of spaces that need improved air exchange.

Suitable for

• Monitoring classroom air quality to manage ventilation breaks
• Checking CO2 levels in offices and meeting rooms
• Assessing indoor conditions in homes and apartments
• Short-term checks in shops, clinics and small public spaces

Key specifications

• Measured parameters: CO2 concentration, ambient temperature, relative humidity
• Display type: digital numeric display
• Mounting: tabletop or shelf placement (portable)
• Intended environment: indoor use

How to use

Place the CO2 monitor on a stable surface at breathing height in the room to be measured, away from direct heat sources, windows and doors that would skew readings. Allow the device a few minutes to stabilise after relocating it before reading measurements. Use the displayed CO2 value together with temperature and humidity readings to determine whether ventilation is required; follow local or institutional guidance for acceptable CO2 levels. For repeated checks, move the monitor to representative locations within the room and note changes over time.

Usage recommendations

For reliable measurements, keep the sensor free from dust and avoid placing the unit in direct sunlight or near heating and cooling vents. Perform measurements after the room has been occupied for several minutes to capture typical conditions. Use the combined CO2, temperature and humidity information to plan ventilation intervals and maintain indoor comfort.
