The RX250AL Receiver logger is the heart of a GenII logging system. It is not necessary to have a PC permanently
connected and the built in battery means data logging is not interrupted if there is a temporary AC mains failure.
Multiple RX250ALs can be used for wide area coverage. Alarms (including SMS alarms) come as standard. (To use SMS
alarms, a GSM modem is required).
