<span style="color: black">請問互用藥劑都不變嗎? 直接讀數乘除85就可以嗎?</span> <br />
<br />
這樣用HI 764測PO4會不會準確些? (因為 ppb * 85 換算ppm 大約可以得到現有 713讀數的1/10 )

可以看這一張表<br />
同樣的NO2試劑，用HI-764跟HI-713所測的結果<br />
<br />
中間那一行，HI-764的數據，除以85再乘以1000，得到右邊那一行的數據<br />
(乘上1000是把單位由ppb轉為ppm)<br />
<br />
HI-764最小單位是1的話，相當於HI-713最小單位的1.18<br />
<br />
所以HI-713多準一點點，可測範圍大一點，其實也沒差多少<img src="/vbb/images/smilies/em04.gif" class="smilie" loading="lazy" alt=":em04:" title="Em04 :em04:" data-shortname=":em04:" /><img src="/vbb/images/smilies/em04.gif" class="smilie" loading="lazy" alt=":em04:" title="Em04 :em04:" data-shortname=":em04:" /></div>
