DFR0300-H, Expansion Board, Gravity Electrical Conductivity Sensor, Arduino and Raspberry Pi Boards
Analog electrical conductivity sensor / meter(K=10) is specially 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. It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board; The excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision and prolongs the life of the probe; The software library uses single-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.
• Output voltage: 0V to 3.2V• AC excitation source, effectively reduce polarization• Gravity connector and BNC connector, plug and play, no welding• Uniform size and connector, convenient for the design of mechanical structures
