Total Dissolve Solid (TDS) meter

Pzsmocn TDS Instrument Sensor,Total Dissolved Solids Measuring Instrument,Can be Applied to Water Quality Detection in Domestic Water,Hydroponics and Other fields,Compatible with Raspberry Pi/Arduino Boards.

Note: When using the TDS instrument sensor, the sensor probe is immersed in liquid, and the purchaser needs to Separate the sensor Probe Protective Cover to avoid incorrect data reading and malfunction.
TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is.
