Valeport Midas ECM

The Midas ECM is a highly versatile point current meter, designed with durability and ease of deployment in mind.


Valeport’s latest electronics architecture allows multiple additonal sensors, and a variety of communications options, making it one of the few multiparameter current meters that allows real time operations over several thousand meters of cable, as well autonomous deployments. The result is a versatile, easy to use instrument, ideal for use by oceanographers, hydrographers and surveyors who require a solid state, multi-parameter current meter.
