Description
The RTR501B is a remote data logger with an internal thermistor sensor. With its compact rugged design and internal temperature sensor, the RTR501B can be used in environments of -40℃ to +80℃ and has an IP67 waterproof rating (immersion proof). The slower response to temperature changes means readings are closer to those of products stored in the refrigerator, or cold stores. The RTR501B’s internal thermistor sensor won’t pick up sudden drop in air temperature when doors are opened to retrieve products but will catch the door being left open, or opened too frequently.

*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: Only “Endless” is available when using the RTR500BW, RTR500BM, RTR-500NW/AW or RTR-500MBS-A as a Base Unit.
*3: There are US models and EU models in the RTR500B Series. They cannot be used together because they have different wireless specifications.
*4: Bluetooth is available when using the RTR500BW or RTR500BM as a Base Unit and making device settings in the mobile app (T&D 500B Utility).
*5: When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For details, contact your local authorized distributor.
*6: RTR-500A2 should not be used with the RTR501B, as it will cause the RTR501B to display a higher than actual temperature reading of up to 3 °C.
*7: 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.
*8: This is the waterproof capacity of the data logger with the sensor connected. Note that the temperature-humidity sensor is not water resistant.
*9: Also compatible with the following discontinued products: RTR-500DC, RTR-500, RTR-500NW/AW, and RTR-500MBS-A.
