Measure Electrical Conductivity in Siemens, Total Dissolved Solids in PPM, and Salinity in PSU.
An electrically isolated I2C sensor device, a waterproof temperature sensor, and an electrical conductivity probe. It measures the conductivity of a solution and converts it into Siemens (S) total dissolved solids and salinity. The firmware allows for single or dual-point calibration with temperature compensation.
