- [中文版](./README_CN.md)

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. <br>
