Cost effective solution to wireless monitoring, includes  sensor requires RTR57U, WDR3 or RTR50 to configure, automatically download, dispatch email alarms and analyse data. Display and collect temperature data, using the wireless RTR-51 datalogger with internal sensor, measure and record temperatures from -40 to 80°C.

The TandD RTR-57C datalogger also allows you to control all recording settings such as start recording and other functions of the data loggers via wireless communication. Moreover, the RTR-5 Series loggers can transmit measurements in the wide range of -30°C to 80°C from distances of up to 100 meters if unobstructed and direct. It is also possible to use in combination with our RVR-52 Wireless Voltage datalogger.

The lightweight yet durable water resistant construction allows you to use this unit under the harshest of conditions. It can be reliably used in high condensation areas, refrigerated and frozen environments as well as underground.

Because wireless communication for all RTR-51,52,53 and RVR-52 units can be made within the wide range of -30 to 80°C, it is possible to use the units to manage temperature in below freezing conditions such as frozen transportation and storage.

Our RTR-5 Series allows you to wirelessly monitor current readings of one group of RTR-5 Series units, with the readings being sequentially displayed on the handheld RTR-57C Unit.

Monitoring intervals can be set on the RTR-57C for 15 and 30 seconds as well as from 1 minute to 60 minutes for up to 64 units in one group. The high-speed communication allows you to collect 64 units worth of data in just 20 seconds. Moreover, the downloaded data is sequentially displayed on the handheld unit for 2 seconds. At the same time, if a set upper or lower limit has been exceeded a warning will be displayed and an alarm sounded.
