Simple but Versatile Four-Item Logger for UV, Illuminance, Temperature and Humidity
The TR-7Ui series, with a simple USB connection to your PC, provides an easy way to make detailed settings and download data. Basic settings and REC start/stop can also be done by simply pressing buttons on the units themselves.
The model TR-74Ui and TR-74Ui-S can not only measure and record UV, Illuminance, temperature and humidity but can also record and display cumulative UV and Illuminance. They are perfect for use in the protection of exhibits and archives in museums and libraries.
The model TR-74Ui-S comes with a high precision temperature-humidity sensor, making it perfect for situations where strict temperature and humidity control is required.
Simply place the TR-74Ui or TR-74Ui-S at the measurement site after starting recording. Recorded data can then be downloaded by connecting the logger to a PC with a USB cable and using the software “Illuminance UV Recorder for Windows”. Data downloaded to your PC can then be viewed and analyzed with our Windows compatible software “T&D Graph”. By connecting a logger to your PC, it is also possible to monitor current readings using our Windows software.

- When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C
- Compared to the value measured by the T&D standard sensor for calibration under our calibration light source.
- Customers wishing to write their own software, please contact your local distributor for the serial communications protocol specifications. (Note: Optional serial communication cable TR-07C is also required.)
- Battery life varies depending upon multiple factors including ambient temperature, recording interval, frequency of communication, and 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.
The specifications listed above are subject to change without notice.
