A733 GSM is a robust, universal radio telemetry unit (RTU) for environmental data acquisition. It combines data logger and data transmission technology in one rugged IP 65 housing and allows for a quick setup of the station in every environment. A733 GSM operates in the GSM frequency band (900/ 1800 MHz) and is designed for professional users who want to collect and transmit a multitude of parameters from remote locations. The device is fully compatible to Adcon’s A840 Telemetry Gateway and can easily be integrated into existing Adcon monitoring networks. Though this A733 version transmits data via GSM it is based on a low-power concept and allows for year-round solar powered operation.
