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.
* Available 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.
“HailSens represents the culmination of years of dedicated research. As the only hail sensor that seamlessly integrates with hailpad data – the gold standard for scientists worldwide.”
“HyQuant Edge is the first radar sensor-based monitoring station for hydrology built on this architecture. Add a SIM card and power, and go from unboxing to live data in minutes.”
“Both Classic and Edge sensors have their place in modern monitoring. The goal isn’t to eliminate choice — it’s to expand it.”
