✔ 最佳答案
你可以去賣化工材料的公司買, 上網就查到, 我知道有門市的就是球興行,在荔枝角道, 他有網站,很容易找到.pH試紙有很多種, 有些一張裡面可以相對準確的測到pH, 有些是測酸,有些是測鹼(即遇到酸或鹼才變色的), 當然比較準確的是比較貴, 我一直是在化驗室工作, 十幾年前買過, 幾十塊錢有一百張(比較準確的)

藥房because when I was a child, I had bought pH paper to have test on many things; I lived in the public housing estate, I just went to the pharmacy in the housing estate to buy them.
