Water Tests to Analyze Water Quality:
PH: Power "Potenz" of Hydrogen.
ISE: Ion-Selective Electrodes.
ORP: Oxidation Reduction Potential.
EC: Electrical Conductivity.
TDS: Total Dissolved Solids.
SS: Solved Solids.
DO: Dissolved Oxygen.
TEMP: Temperature.
COD: Chemical Oxygen Demand analysis by two different methods:
1- CODCr: the dichromate method.
2- TiO2/UV: photoelectrochemistry (the PeCOD™ method). Color, Turbidity, Salinity, CL-, PO4, NH3,NO3 and etc.

- TDS = keEC (ppm or mg/L), The correlation factor ke varies between (0.4 - 1.0) (default value for AD332: 0.5)
- Salinity was based on chloride concentration: S = 1.80655*Cl
- TDS meters can be used to test for Salt (up to the maximum range of the meter). Salt is a part of Total Dissolved Solids and therefore will be part or all of the reading. If you are first filtering the water, and then adding salt, simply use the meter as you would under any circumstances. If there is only salt in the water, and the reading is 2500 ppm, then the it is 2500 ppm (mg/L) of salt.
- The USA, Environmental Protection Agency (EPA), the World Health Organization (WHO) and most nations put maximum limitations on TDS allowed in drinking water from 500 to 1000 ppm.
- If you drink 1 liter of water a day, your body will have processed 25567 liter of water over a 70 year span. If the water is not totally pure, this 25567 liter will include (20 - 30) Pound of rock that the body cannot utilize. Most will be eliminated through excretory channels. But some of this will stay in the body, causing stiffness in the joints, hardening of the arteries, kidney stones, gall stones and blockages of arteries, microscopic capillaries and other passages in which liquids flow through our entire body.
So that care about the water that you drink.
