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.   Key features Self recording and/or direct reading Discus EM sensor [annular and spherical options Flux gate compass Continuous and burst sampling Optional Conductivity, Temperature, Pressure, Pitch/Roll sensors Optional built in auxiliary sensor port Fast Response PRT Temperature sensor Pressure balanced inductive conductivity sensor Valeport EMLog″!
