About these items Accurate CO₂ detection: Use dual infrared sensors to precisely measure CO₂ levels within the range of 400 - 5000ppm. Simultaneously display temperature and humidity, providing clear and stable data about the indoor environment. Compact & portable: Lightweight design, with weights ranging from 0.29 lbs (0.13 kg) to 0.46 lbs (0.21 kg), making them easy to carry in hand, pocket, or bag. Ideal for monitoring air quality in various indoor and some outdoor spaces like classrooms, offices, greenhouses, or labs without space or power access constraints. Long - lasting battery: Equipped with either a 1000mAh or 2000mAh battery, providing continuous operation for 72 - 120 hours. This extended battery life reduces the need for frequent charging during long - term mobile monitoring. Real - time monitoring: High - sensitivity infrared sensors measure CO₂ in real - time. Multi - color indicators (and color - coded lights in one model) help visually assess air quality and guide ventilation decisions. One model also offers WiFi connectivity for remote monitoring. User - friendly operation: No complex setup required. Power on and wait 10 seconds to start monitoring. A large display shows CO₂ concentration, temperature, and humidity, and user - friendly buttons ensure smooth and quick operation.
