The Uni-T UTA37 is a versatile and essential tool for monitoring indoor air quality. Designed with precision in mind, this compact device utilizes advanced NDIR (non-dispersive infrared) technology to detect carbon dioxide concentration levels ranging from 400ppm to 5000ppm. Whether you are managing an office, a classroom, or a residential space, the A37 provides the real-time data needed to ensure a healthy environment.

Equipped with a large, clear LCD screen, the unit simultaneously displays CO2 levels, ambient temperature, and relative humidity. To make air quality assessment even easier, it features intuitive emoticons that indicate air status at a glance. When CO2 levels rise beyond safe thresholds, the device triggers both audible and visual alarms, prompting immediate action such as increasing ventilation.

Why It Matters

High concentrations of CO2 in indoor environments are often linked to poor ventilation, which can cause headaches, fatigue, and reduced productivity. By using the Uni-T A37, you can proactively manage air flow, ensuring that occupants remain comfortable and healthy. Its automatic baseline correction ensures that the sensor remains accurate over long periods, making it a reliable set-and-forget solution for air quality management.
