RTR503BL Temperature and Humidity Data Logger (0-55°C, 10 to 95%RH), battery life of up to 4 years

RTR503BL loggers have a wireless radio communication range with compatible base units of up to 150m (500ft).
Data can be transmitted from a logger to a base unit and then automatically uploaded to cloud storage or saved to a specified location. Data can also be checked on your PC screen or on site with one of our compatible data collectors.
The RTR503BL with its wireless radio communication capabilities is perfect for applications where temperature and humidity at various measurement points are managed at once, such as in temperature-controlled storage facilities and warehouses.
The large capacity battery (not included) reduces the risk of data loss and lessens the troubles of changing batteries.
