Overview of the TandD TR-76Ui Indoor Air Quality Data Logger
The TandD TR-76Ui is a compact three channel data logger that measures and records temperature, humidity, and CO2 concentration. This easy-to-use logger connects to your PC with a USB cable and is configured using software. Additionally basic settings and record start/stop can be performed using buttons on the device. The TR-76Ui is perfect for use in monitoring and managing indoor air quality (IAQ). The logger features an alarm output which can be connected to trigger an external buzzer or visual alarm indicating high concentrations of CO2. This information can be used to notify occupants when additional ventilation is needed. CO2 loggers such as the TR-76Ui are currently being utilized to reduce the spread of COVID-19 by ensuring proper ventilation levels.
