TR-74Ui USB Connected Illuminance & UV Recorder - Tech Instrumentation

TR-74Ui USB Connected Illuminance & UV Recorder

  • $299.00


TR-74Ui and TR-74Ui-H Illuminance UV Recorders

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.

The product is an all-in-one package that includes the data logger unit, sensors and software. We offer two types of packages with different temperature/humidity sensors depending on your required measurement range and accuracy needs.
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.

Not only can recorded data be easily downloaded to a PC via USB communication, but it can also be collected from data loggers via infrared communication to our T&D Data Collector TR-57DCi (optional, sold separately). The TR-57DCi enables the user to gather and check recorded data on the spot without having to manually gather the data loggers and connect to your PC via USB.

  • *1) When used in environments where temperature and humidity are over the values of 50 °C 75%, 60 °C 50%, 70 °C 35%, and 80 °C 25%, sensor hysteresis may fluctuate by values greater than ±1.5%RH. Under certain circumstances, it may take some time to return to normal measurement capability.
  • *2) Compared to the value measured by the T&D standard sensor for calibration under our calibration light source.
  • *3) Only "Endless" is available when using RTR-500W for Windows.
  • *4) If necessary, serial communication can be established by using our communication protocol (contact your local distributor) to write a software program. In such a case, an optional serial communication cable (TR-07C) is needed.
  • *5) Battery life varies depending upon the ambient temperature in which it is used, the recording interval, the frequency of communication, and the battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life. When infrared communication function is enabled, battery life may be shortened if the unit is used under the inverter type fluorescent lighting.
