TR-74Ui-S T&D Accumulating Light, Humidity and Temperature Data Logger Product ID: TR-74Ui-S (with higher accuracy SHA-3151)

Overview

Product Type: TR-74Ui

The ""TR-74Ui 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.
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 (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.

Application Examples
* In art museums and other exhibit forums to manage illuminosity and help prevent deterioration of exhibits
* Management during all aspects of plant and food production
* For use in the development, testing, manufacture and sales of products for cutting UV rays
* UV reduction management in schools from kindergartens to universities
* For home and office use in the management or illuminosity and UV rays
* Design and management of homes and architectural buildings
* For managing the reduction of UV rays at swimming pools, the ocean, mountains and in parks
* For management and adjustment of illuminosity for photography and film
* For management in the production, storage and sales of foodstuffs and beverages
* For use at supermarkets, convenience stores and drugstores in UV product sales promotion materials


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

  • *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.

Connecting more than one TR-74Ui Unit at a time can only be done if using Windows 7 and Windows Vista.
This is an image showing a modern art gallery showing an exhibition on brightness and UV management. The gallery uses large areas of UV-filtered glass windows and strategically placed LED lighting to protect the artwork, as well as information panels explaining the importance of light management in preserving art. Part of the gallery houses a greenhouse area illustrating the use of natural light management in maintaining plant health. The entire space is clean and modern and filled with visitors admiring the artwork and greenhouse plants.Light Meter data logger at art gallery
