MD14 - Viewer for 28 probes cathodic protection system survey
The MD14 viewer for cathodic protection systems is a compact and inexpensive device aimed to efficiently solve the problem of displaying the P.D. (Potential Difference or Voltage Gradient) in a survey system of 14 reservoirs, requiring cathodic protection from a single power supply (outside the unit).
The device accepts up to 28 input probes (2 per tank) and displays the P.D. of each tank compared with the selected probe. With MD14 the operator can evaluate at a glance the overall situation of the system, and choose the probe to connect to the power supply input.
