Clear- TDS: Measures the total amount of dissolved solids and is used for a quick assessment of water purity and dissolved content.
- EC: Measures the electrical conductivity of water, that is, its ability to conduct electric current due to the presence of dissolved ions, and is used to monitor the concentration of salts and nutrients.
- pH: Measures the acidity or alkalinity level of water on a scale from 0 to 14, where values below 7 indicate acidic water, a value of 7 is neutral, and values above 7 indicate alkaline water.
- Temperature: Measures the water temperature, which significantly affects other quality measurements such as pH, conductivity (EC), and dissolved oxygen.
- ORP : Measures the oxidation-reduction potential (ORP) of water, that is, its tendency to oxidize or reduce substances. It is used to assess the disinfecting ability and chemical stability of water (e.g., in swimming pools, water treatment, and aquariums).
