<p>在線氨氮測定儀采用水楊酸-靛酚藍(lán)法測定氨氮濃度，由于催化劑的作用，NH4+在堿性介質(zhì)中，與次氯酸根離子和水楊酸鹽離子反應(yīng)，生成靛酚化合物，并呈現(xiàn)出綠色。在氨氮檢測儀測量范圍內(nèi)，其顏色改變程度和樣品中的NH4+濃度成正比。因此，在線氨氮測定儀通過測量顏色變化的程度計(jì)算出樣品中NH4+的濃度，從而實(shí)現(xiàn)氨氮的測定。</p><p>

</p><p>　　其中，比色的原理是：氨氮在水中會(huì)與納氏試劑或者水楊酸鹽試劑形成穩(wěn)定的色差變化，這個(gè)變化與氨氮的濃度成正比例關(guān)系。</p><p> </p><p>　　傳感器法的原理是：首先測量樣品的初次電位值E1，然后根據(jù)此數(shù)值添加一定體積已知濃度的標(biāo)準(zhǔn)溶液，再次測量該混合溶液的電位值E2，根據(jù)兩次測量的差值帶入公式計(jì)算出樣品濃度。</p><p> </p><p>　　獨(dú)立的取樣管路</p><p>
