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

• *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.
