Description

The TR-74Ui Temperature Humidity Light Data Logger can simultaneously measure and record illuminance, ultraviolet light (UV), temperature and humidity. In addition to these, the TR-74Ui Temperature Humidity Light Data Logger is also capable of displaying cumulative illuminance and cumulative amount of ultraviolet light in the LCD display.

The product is an all-in-one package that includes the data logger unit, sensor and software. By simply connecting to a PC via a USB connection and carrying out a few easy steps, the measurement and recording of data can be started.
