Description

The RTR-574-S is a high precision logger which will measure and record UV, illuminance, temperature and humidity. Cumulative UV and illuminance can also be logged and displayed. The RTR-574-S can be used to monitor environmental conditions in museums and libraries of either exhibits or archive storage areas.

*1: When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20°C.
*2: Compared to the value measured the T&D standard sensor for calibration under our calibration light source.
*3: Only “Endless” is available when using the RTR500BW, RTR500BM, RTR-500NW/AW or RTR-500MBS-A as a Base Unit.
*4: There are US models and EU models in the RTR500B Series. They cannot be used together because they have different wireless specifications.
*5: The listed battery life is based on the following usage conditions: Recording at 10 second (or longer) intervals, Current Readings Transmission every 10 minutes, and Recorded Data Transmission once a day. Battery life also varies depending on ambient temperature, radio environment, frequency of communication, etc.
*6: Also compatible with the following discontinued products: RTR-500DC, RTR-500, RTR-500NW/AW, and RTR-500MBS-A.
