Illuminance & UV Intensity
The "Illuminance UV Recorder" is a data logger designed to
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.
