Accumulating Light, Humidity and Temperature Data Logger ( TR-74Ui) - TR-74Ui

TandD TR-74Ui Accumulating Light, Humidity and Temperature Data Logger recorder

Product Type
Measurement Items
The "TR-74Ui Illuminance UV Recorder" is a USB-dedicated data logger which can simultaneously measure and record four items: Illuminance, Ultraviolet Light (UV), Temperature and Humidity. In addition to these, the TR-74Ui is also capable of displaying Cumulative Illuminance and Cumulative Amount of Ultraviolet Light in the LCD display. From dim moonlight to the summer sun, Illuminance can be measured within a wide range.

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