DFRobot Gravity: analog electrical conductivity sensor/meter(K=10) is particularly used to measure the high electrical conductivity liquid, such as seawater, concentrated brine, etc. The measurement range is up to 100ms/cm. This product is suitable for the water quality application of mariculture, for example, marine fisheries, marine aquariums. you may also check liquid sensor selection guide to get better familiar with our liquid sensor 
It supports 3~5v wide voltage input and is compatible with 5V and 3.3V main control boards, such as arduino and raspberry pi. The excitation source adopts an AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe; The software library uses a single-point calibration method, and can automatically identify a standard buffer solution, so simple and convenient.


  1. 3.0~5.0V wide voltage input,0~3.2V output voltage, which is compatible with 5V and 3.3V mainboard
  2. AC excitation source effectively reduces polarization
  3. Gravity connector and BNC connector, plug and play, no welding
  4. The software library supports single-point calibration and automatically identifies standard buffer solutions, integrates temperature compensation algorithm
  5. Uniform size and connector, convenient for the design of mechanical structures
