IDEALHOUSE #ad - To better understand the range in pH, coffee 5. 5, milk 6. 2, baking soda 8. 5, take a look at these examples: apple juice 3, bleach 12. Very important tips: the water may be corrosive if the tds level is very low. Service and warranty:we will try to respond within 8 hours and offer lifetime technical support.

Healthy ph value of drinking water: a ph value of 7 means a substance is neutral. Function of tds meter: nsf international stated a TDS meter is not necessary. Which kind of water to choose: consuming excessively acidic or alkaline water is unhealthy, warns the Environmental Protection Agency EPA. However, it can certify whether there are some excessive contaminants like heavy metals. The lower value indicates acidity, orange juice 3.

5, soapy water 10, and a higher value is a sign of alkalinity. Drinking water must have a pH value of 6. 5-8. 5 to fall within EPA standards. The corrosive waters may leak the toxic metals from the household plumbing. So, the initial recommendation would be to get your water tested and determine the general quality and chemistry of your water. Do this before consuming or installing your water treatment system.
