The data loggers of the MDL family are reliable everywhere, where measuring data have to be precisely gathered, saved, processed and documented under extreme environmental conditions. The MDL 8/3, the most comprehensive data logger has got eight analogue inputs and three for wind parameters.


The MDL 8/3 has been developed for comprehensive request for environmental monitoring. It is a station manager to establish big or spread measuring stations. With a robust, reliable and economic design and technics, the MDL 8/3 is optimized for the usage in remote areas off any infrastructure. To fulfil specific requirements of measuring the data logger has a variety of functions for gathering, saving, alarming, managing and transferring of measurement data. For the operation in the field, the data logger mostly comes in a switch cabinet. Optionally the functions of the MDL 8/3 can be extended by up to 40 analogue inputs and two serial interfaces by the add-on modules MDL-AE4 or MDL-AE8.
