Simultaneously View Four Measurement in One Easy-to-Read GraphThe recorded data downloaded from TR-74Ui Units is read by the Multi-scale Graph and the data of four items, Illuminance, Ultraviolet Light (UV), Temperature and Humidity, can be simultaneously viewed in graph or tabular form as well as printed or output.page topLarge Data Capacity: 8,000 Readings x 4 Channels The TR-74Ui Illuminance UV Recorder has four channels and can record the measurement of Illuminance, Ultraviolet Light, Temperature and Humidity. Each channel can record and store up to 8,000 readings. At the longest recording interval of 60 minutes, a Unit can record one year's worth of measurements. * The battery life for a TR-74Ui Unit is about 6 months. In order to record measurements consecutively for 1 year, the battery should be periodically changed. Battery life varies depending upon the type of battery, the battery performance, the measuring environment, and the frequency of communication.page topTransmit Recorded Data to PC via USB Connection It is possible to connect a TR-74Ui Unit directly to your computer with a USB cable. If the computer has more than one USB port, it is possible to connect multiple TR-74Ui Units to one computer at the same time. Connecting more than one TR-74Ui Unit at a time can only be done if using Windows 7 and Windows Vista.

Moreover, it is possible to gather current readings from the TR-74Ui connected to your computer and view those readings in the computer display.
