WEATHERPROOF DATA LOGGER WITH INTEGRATED DATA TRANSMISSION
Collecting, processing, storing and transmitting of monitoring data - easy, convenient and quick. The MRL-8 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-8 for data applications in remote areas far from any infrastructure.
- Weatherproof logger with integrated remote data transmission using 2G / 4G modem
- Reliable and energy-saving: optimised to collect environmental monitoring data in remote areas without any infrastructure
- Logger can be operated fully independently (with batteries or solar module), integrated solar charge controller, protection IP 67
- Ideal integration and compatibility with complete SOMMER sensor family as well as popular sensor technology products
- Backlit display for easy data reading and logger parameterisation
- Parameterisation via RS-232, Bluetooth, USB, Ethernet*
- Data readout with USB memory stick or Bluetooth-interface or USB or RS-232
- Minimum energy demand; integrated solar charge controller
- Solid, compact, and weatherproof aluminium box (powder coated)
- Remote data transmission using 2G / 4G modem, Ethernet*, USB-Stick, Satellite (INMARSAT)
*... on specific versions
Similar to the "smaller" MRL-6, also the MRL-8 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-8 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.
