Description

MAIN FEATURES 

CTD multiparametric probes allow the following water quality parameters to be measured:

  • (C) Conductivity
  • (T) Temperature
  • (D) Depth (hydrometric level with differential pressure sensor and cable with barometric compensation tube)

Temperature dependencies and nonlinearity are compensated by a mathematical model developed in the internal microcontroller.

The built-in Pt1000 temperature probe achieves an accuracy of ±0.1°C while for conductivity an accuracy of ±2.5 percent of the selected range (0.2 / 2 / 20 / 200 mS/cm) is achieved. The probes are supplied with a galvanically isolated RS485 serial interface.

The measuring probe is housed in a submersible stainless steel case and is externally powered by stabilized 12Vdc; data acquisition, recording and transmission is done on the Geoves external data logger, which provides functional and storage autonomy for long time intervals. 

These features ensure high reliability and durability resulting in less maintenance required.

 

ADVANTAGES 

  • Minimal maintenance
  • Good measurement resolution
  • Excellent robustness
  • Probe diameter < 1"
