TR-74Ui USB Connected Illuminance & UV Recorder

TR-74Ui and TR-74Ui-H Illuminance UV RecordersThe TR-74Ui and TR-74Ui-H are data loggers which simultaneously measure and record four items: Luminescence, Ultraviolet Light (UV), Temperature and Humidity plus Cumulative Luminescence and Cumulative Ultraviolet Light in the LCD display. The product is an all-in-one package that includes the data logger unit, sensors and software. Choose from packages with different temperature/humidity sensors depending on your required measurement range and accuracy needs. Data can also be collected from data loggers via infrared communication to our TR-57DCi (optional, sold separately). Application Examples Art museums to help prevent deterioration of exhibits Plant and food production Development, testing, manufacture and sales of products for cutting UV rays UV reduction management in schools from kindergartens to universities Management and adjustment of luminosity for photography and film Management in the production, storage and sales of foodstuffs and beverages Supermarkets, convenience stores and drugstores in UV product sales promotion materials  Specifications Product TR-74Ui TR-74Ui-H Temperature/Humidity Sensor (External) THA-3151 HHA-3151(High-Precision Type) Thermistor Polymer Resistance Platinum Resistance Electrostatic Capacitance Measurement Channels Temperature Humidity 1ch Temperature Humidity 1ch Units of Measurement °C, °F %RH °C, °F %RH Measurement Range 0 to 55 °C 10 to 95 %RH -30 to 80 °C 0 to 99 %RH Accuracy ±0.5 °C ±5 %RH (at 25 °C, 50 %RH) ±0.3 °C (at 10 to 40 °C) ±0.5 °C (at all other temperatures) ±2.5 %RH(at 25 °C, 10 to 85 %RH) ±4.0 %RH(at 25 °C, 0 to 10 % or 85 to 99 %RH) At temperatures other than 25 °C and  0 °C, add ±0.1 %RH per degree of difference from 25.

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.
