A key performance indicator, or KPI for short, is one gauge of how well your business is hitting its performance targets. Profit, sales growth, and employee retention are popular KPIs, but you can’t really determine what appropriate KPIs are for your company until you do some goal-setting....
The value of pH tells the strengths of acids and bases quantitatively. It is a universal indicator that shows different colours for different concentrations of hydrogen ions in a solution. An optimum or balanced value of pH shows good health. The pH or level of hydrogen in our body is based...
In fact, the TDS level is a good indicator of whether or not drinking water is suitable for human consumption. It also tests whether a certain water quality needs a rigid filtration system or is highly contaminated. But, it can be harmful when taken more than the desired amount...
