USB CO2 data logger designed for accurate monitoring of CO2, temperature and humidity in indoor environments.
The TR-76Ui is a temperature humidity CO2 logger that records three measurement channels at once, using an internal NDIR CO₂ sensor and a supplied temperature‑humidity sensor. Simple USB connectivity allows quick setup, data download and live monitoring via Windows software, while built‑in warning outputs support timely ventilation control.
