About this product This CO₂ monitor precisely measures carbon dioxide concentrations in the range of 400 to 5000 ppm and helps to continuously monitor indoor air quality. Two infrared sensors ensure stable and accurate measurements while simultaneously displaying temperature and humidity. This combined display provides users with a comprehensive overview of the indoor climate. The clear display shows all measurements clearly and facilitates a quick assessment of current air conditions in homes, offices, or classrooms. Thanks to its lightweight and compact design, this air quality monitor is easy to transport. Depending on the model, the device weighs only about 0.13 kg or 0.21 kg and can be conveniently carried in one hand or stored in a bag. This makes the monitor ideal for use in various locations, such as offices, schools, greenhouses, laboratories, or living spaces. The compact design saves space and allows for flexible monitoring of indoor air quality. Equipped with a powerful 2000 mAh or 1000 mAh lithium battery, the device offers an operating time of approximately 72 to 120 hours. This long runtime reduces the need for frequent charging and enables long-term air quality monitoring. This makes the CO₂ monitor particularly well-suited for workspaces, classrooms, greenhouses, or other environments where continuous measurement is required. The integrated infrared sensor instantly detects changes in CO₂ concentration and displays the values in real time on the screen. Color-coded indicators further facilitate a quick visual assessment of air quality. Some models also offer a Wi-Fi connection, allowing users to monitor air conditions remotely. This feature enables convenient monitoring of the room air without having to be directly next to the device. The CO₂ meter is user-friendly and requires no complicated setup. After being switched on, the device begins measuring air quality within seconds. The large display simultaneously shows the CO₂ concentration, temperature, and relative humidity. Intuitive control buttons ensure easy operation, making the device suitable for both home and office use. Key Differences The PTH-9CW model features Wi-Fi connectivity, allowing users to monitor air quality remotely. The PTH-9C model offers similar measurement capabilities but lacks Wi-Fi connectivity and focuses on displaying air quality data directly on the device. The PTH-10C model is more compact and lightweight, with a smaller 1000 mAh battery, making it particularly portable and easy to transport.
