Overview of the TandD TR-76Ui-S Wide Range Indoor Air Quality Data Logger
The TandD TR-76Ui-S is a compact three channel data logger that measures and records wide range temperature, wide range 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-S 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-S are currently being utilized to reduce the spread of COVID-19 by ensuring proper ventilation levels.
