Easily check a room’s ventilation to prevent health hazards and the spread of airborne infectious diseases.
Marvel 001 allows you to easily check a room’s ventilation to prevent health hazards and the spread of airborne infectious diseases. Marvel 001 is ideal for visually verifying indoor ventilation anywhere, such as homes, offices, schools, commercial facilities, hospitals, and care facilities. Marvel 001 has a high-accuracy NDIR (non-dispersive infrared) dual-beam sensor that prevents measurement errors even with long-term, continual use. We can assure quality by producing our product in Japan.

Reason for Development
High concentrations of CO2 can cause drowsiness, headaches, and other health problems. But CO2 is a colorless and scentless gas that humans cannot detect on our own. That is why we developed Marvel 001 to detect CO2 levels and enable you to know when to further ventilate your room.
