CURRENT METER
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 additional sensors, and a variety of communications options, making it one of the few multiparameter current meters that allows real time operations over several thousand metres of cable, as well autonomous deployments. A choice of titanium or acetal housing gives depth rating up to 5000m.
