The RTR-500GSM is a mobile base station that is equipped with GSM phone network capabilities, which creates unprecedented flexibility for monitoring and collecting data from just about anywhere. Designed for monitoring the real-time conditions of products while in transit or in remote areas, the unit communicates wirelessly with the RTR-500 series loggers and then transmits the data through the GSM cell network. It automatically sends warnings via e-mail or SMS (text message), when a measurement exceeds preset limits, enabling the user to know about important changes in product conditions right away.

The data collector operates using a SIM card from a GSM compatible cell phone company or carrier (AT&T and T-Mobile are the largest GSM companies). As long as you are in range for cell service, simply place this unit in the truck's cab and a remote logger in the trailer and you are ready to monitor temperature and humidity while on the move. The unit will operate with virtually any AT&T cell phone SIM card as long as the account has SMS and data capability. While the unit can operate with a voice account SIM, it only uses the data functions and not voice minutes.
