- • Best for: Families, office managers and teachers performing quick ventilation checks
- • Not ideal for: Continuous cloud logging or advanced smart-home integration needs
Real-time monitoring of CO2, temperature and humidity with portable design. Colour-coded alarms and optional audio warnings simplify decision making about ventilation.
Clear, actionable air alerts – Thanks to colour-coded alarms and optional audio warnings
Multiple alarm modes use preset concentration thresholds and colour-coded visual cues, with an option for audio warnings. A dedicated 'no disturb' mode silences sound alarms and reduces light emissions for night use.
Instant visual and audible signals show when ventilation is needed, suitable for bedrooms, classrooms and shared offices. Silent mode keeps monitoring active without disturbing occupants.
Long standby for portable checks – Thanks to Photoacoustic CO2-Sensor and intelligent algorithms
A Photoacoustic CO2-Sensor combined with intelligent algorithms supports dual detection modes and energy-efficient operation, enabling extended standby periods. The specification cites standby time of up to 70 days under low-use conditions.
Carry between rooms or leave on a shelf for days without frequent recharging, ideal for intermittent spot checks. For continuous, up-to-the-minute readings, keep the unit plugged in via USB.
Discreet, flexible placement – With detachable stand, adsorptive back and compact design
Compact housing includes a detachable stand and an adsorptive back for temporary wall mounting or desk placement. Low-light operation and minimal emissions in 'no disturb' mode reduce visual impact at night.
Place on a bedside table, attach to a wall in a classroom or carry between rooms without fuss. Night-time monitoring becomes practical thanks to reduced light and silence options.
