arv k14

Autonomous roughness recorder ARV-K14. Autonomous roughness recorder uses for autonomous control  of roughness on the high seas.

Applications

Autonomous roughness recorder uses for autonomous control  of roughness on the high seas. Roughness recorder consists of quarts pressure and temperature  transducers  PDTK-P-M by SCTB  ELPA, frequency counter, semi-conductor memory with electric clock and storage battery, placed in cylindrical  stainless steel case. Recorder can be used for the control of relief changing of littoral shelf and destruction of the shore edge. 

Features

  • Refer to hydrological equipment;
  • Having  protection from sweet and sea water;
  • Completely autonomous during long time (till 400 days);
  • High accuracy pressure measurement;
  • Stainless steel case.
