The RTR-574 includes two sensors that simultaneously measure and record Illuminance / UV intensity and temperature / humidity. This Data Logger allows for the measuring and recording of the above items in various places such as facilities where people gather, where important documents and fine arts are being stored or displayed, where food and drink is being stored. The possibilities are endless! Also, cumulative illuminance and the cumulative amount of UV light can be easily viewed even without stopping recording.

*RTR-574 Data Loggers (Remote Units) can be used with the following as a Base Unit: RTR-500AW, RTR500NW, or RTR-500.

* Neither the RTR-574 Unit nor the included Sensor is waterproof.

The RTR-574 uses one AA alkaline battery. If one Unit of full data is downloaded once a day via wireless communication, the estimated battery life will be about four months. (There is no L-type model for RTR-574.)

The buttons on the face of the RTR-574 Unit make it possible to change the LCD display pattern, start and stop recording, make or change recording interval settings, and turn power ON or OFF.
To prevent unexpected errors in button operation, you can use the software supplied with the Base Unit to lock the button operation.

(1) Compared to the value measured by the T&D standard sensor for calibration under our calibration light source. (2) Up to four digits are valid for the Current Readings and Cumulative Measurements. (3) The same amount of time will be necessary for each added Repeater. (4)Battery life varies depending upon the measuring environment, the communication frequency, and the quality of the battery being used.
