Indicates waters acidity and helps determine if water will corrode plumbing. Hard water is water that has high mineral content in contrast with soft water. Hardness is one contaminant you will also commonly see on the report.
After 2-3 seconds the display will light up and read 00 so you can start using the meter.
These ions do not pose any health threat but they can engage in reactions that leave insoluble mineral deposits. Because two of the trials showed results of 200 ppm and one had the result of 210 ppm this indicates that the actual hardness of the water was closer to 200 ppm. After running the initial set of tests well users should continue to test for bacteria once a year. 260mgl CaCO3 7.
