  • *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 For communication with the Data Collector RTR-500DC (Note: Optional serial communication cable TR-6C10 is required.
  • *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.
