[問] 可測試飲用水水質的杯子...?
在PCHome看的這東西 覺得很有意思
說是可以測試水質好壞 http://shopping.pchome.com.tw/water...hp?pid=WPF00015 然後又找了一下 發現有這個同類產品 http://osc.waterangel.net/product_i...&products_id=66 請問一下 這東西的原理為何？ 好像是測量水的導電程度 來量出水的硬度？ 又以上兩種商品有何差別？ 此文章於 2004-11-12 11:19 PM 被 Lucica 編輯. |

純水,是幾乎不導電的
但若是加入雜質如礦物質等,就會提高導電性 這個就是藉由測導電性來測量水質,越小水中的雜質越少
