Wireless Temperature Data Logger -- TandD RTR-501 -- View Larger Image

The RTR-501 Wireless Temperature Data Logger with internal sensor provides optimum waterproof and dustproof capabilities. This is the perfect data logger for use in harsh environments: whether that may be indoor frozen or refrigerated storage or high humidity, high dust outdoor applications. Moreover, the compact lightweight design means it can be placed just about anywhere.

Download Data via Wireless Communication with a Base Unit

Recorded data can be downloaded from the TandD RTR-501 data logger (Remote Unit) via wireless communication with a Base Unit. The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft]. By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.

Large Logging Capacity: Up to 16,000 Readings

16,000 readings means you can record every one second and still log four and a half hours of data, or at a recording interval * of 60 minutes you can keep logging for 666 days. A Base Unit can download via wireless communication one RTR-501 Remote Unit at full logging capacity (16,000 readings) in about two minutes.

Low Energy Consumption Design

The RTR-501 Wireless Temperature Data Logger uses one Lithium Battery (LS14250). At normal temperature, if recorded data is downloaded once a day or if monitoring is carried out once every ten minutes, the estimated battery life will be about ten months. Model names which include “L” are designed with a large capacity battery pack. Under the same conditions, L-type models will continue for about four years without the need to change the battery.

Battery life varies depending upon the type of battery, the measuring environment, and the frequency of communication. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
