Announcing our New TR-74Ui Data Logger: For Illuminance, Ultraviolet Light, Temperature and Humidity

T&D Corporation is proud to announce that our new "TR-74Ui Illuminance UV Recorder" will be available from January 2010.

The "TR-74Ui Illuminance UV Recorder" can 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.

The product is an all-in-one package that includes the data logger unit, sensor and software. 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.

Features

  • With just one unit it is possible to measure and record Illuminance, Ultraviolet Light, Temperature and Humidity.
  • Possible to view Cumulative Illuminance and Cumulative Amount of Ultraviolet Light in the LCD display
  • Illuminance can be measured within a wide range (from dim moonlight to the summer sun)
  • View and record Illuminance in resolutions to 0.01 lx.
  • Possible to measure and record up to 8,000 readings per measurement item.
  • Simultaneously view all four measurement items in one easy-to -read Graph.
  • Transmit recorded data to PC via USB connection.

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
  • 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
