Opis

WEATHERPROOF DATA LOGGER WITH INTEGRATED DATA TRANSMISSION

Collecting, processing, storing and transmitting of monitoring data – easy, convenient and quick. The MRL-7 is a battery run data, modem supported logger with splash-proof housing, USB data read-out functions and integrated solar charge controller. The very energy efficient operating mode as well as a weatherproof box qualifies the MRL-7 for data applications in remote areas far from any infrastructure.

FIELDS OF APPLICATION

Similar to the “smaller” MRL-6, also the MRL-7 is used for applications in environmental monitoring, where low maintenance and a very energy saving operation is needed as for example at sites with no landline power network or where no additional switch cabinet shall be installed. The MRL-7 provides comfortable data transmission through its integrated modem. For this reason all-in-one solutions (sensor, data collection and transmission) can be realised very easily. In addition, remote access as well as wireless data read out and storing are possible.
