High Precision Wide Range Temperature and Humidity Data Logger: RTR-507

The Wireless Data Logger RTR-507/507L is a new model in our lineup of RTR-500 Series, which enables wide range high precision measurements of temperature and humidity.
We achieved a humidity measurement accuracy of ±2.5%, as well as wide range measurements of temperature from -30 to 80℃ and humidity from 0 to 99%RH.
By using our RTR-500 Series Base Unit, the recorded data in the RTR-507 not only can be collected via wireless communication, but can also be used for data monitoring, warning monitoring, and data management through networks to construct a data logging system to match your needs and environment.

※ Note that the RTR-507L is an extended battery life type.

  • (*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) Only "Endless" is available when using RTR-500W for Windows or RTR-500MBS for Windows.
  • (*3) When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For details, contact your local authorized distributor.
  • (*4) Battery life varies depending upon the ambient temperature in which it is used, 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.
  • (*5) When wireless communication is performed in an environment below -10°C, measurement may fail or may not be accurate.
  • (*6) This is the waterproof capacity of the data logger with the sensor connected.
