MIDAS CTD Profiler

All Valeport CTDs use our own inductive conductivity sensors. Digital sampling techniques ensure high accuracy, and the unique construction gives sensor stability at any depth

Add to Request

The MIDAS CTD (previously known as the Model 606) is Valeport’s premier CTD Profiler. High accuracy sensors (including ±0.01% pressure) and robust titanium design allow reliable operation to 6000m depth, under the harshest conditions. It also features truly synchronised sampling to ensure that all sensors are sampled at exactly the same point during a profile. Primarily for use as a self recording profiler, the MIDAS CTD also has a range of communications options for real time use, and the low power consumption and large memory also make it suitable for longer term deployments.
