但我用kh pen 有我144us/cm.or 7.5f度呀.why??

The following information from the Water Supply Dept (http://www.info.gov.hk/wsd/wq/DrinkingWater2002e_3c.pdf). Water hardness (Total Alkalinity) is between 3-82 mg/L, average 28 mg/L. Converting to dH 0.3-8.2, average 2.8. I live in Ma On Shan, the pH is about 8.2 and water hardness 8 dH.

the water in my home is also ph 8.2, ha! my ph pen is okey !

Wow! never know the Water Supply Dept have this kind of information... seem our water have some 微量元素 ...
