Multiparameter air quality monitor that helps you see and manage the air you breathe Key benefits Know when to act: Realtime readings for CO2, HCHO (formaldehyde), TVOC, temperature, and humidity let you decide when to ventilate, clean, or avoid a space. Reduce health risk and discomfort: Continuous monitoring helps limit exposure to common indoor pollutants and maintain comfortable temperature and humidity levels. Easy to use: An LCD display provides clear, immediate values so you can assess conditions at a glance. What it does (functions and performance) Measures CO2, formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity with precision sensors for reliable, realtime data. Precision sensors and live readout enable practical, evidencebased decisions about ventilation and indoor air management. LCD display shows current air quality levels and environmental conditions for straightforward interpretation. Practical attributes Multiparameter monitoring combines gas and environmental sensing in a single device, avoiding the need for multiple instruments. Designed for everyday use at home, in the office, and outdoors for spot checks or ongoing monitoring. Simple, readable LCD output keeps information accessible without technical expertise. Use scenarios After renovations or furniture: Monitor HCHO and TVOC levels to judge whether offgassing from paints, adhesives, or furnishings has decreased to acceptable levels. Shared indoor spaces and workplaces: Track CO2 and humidity to determine when to increase ventilation or adjust HVAC settings for comfort and productivity. Outdoor spot checks: Verify local air quality near busy roads, construction sites, or school grounds to inform shortterm exposure decisions. Why choose this monitor Consolidates multiple important air quality and comfort metrics in one device. Precision sensors and an LCD display provide clear, realtime information you can act on. Practical for residential, commercial, and outdoor use without requiring technical training.
