1—獨(dú)特的設(shè)計(jì)，使本產(chǎn)品較之同類(lèi)產(chǎn)品具有更低故障率、更低維護(hù)量、更低的試劑消耗量以及更高的性價(jià)比和準(zhǔn)確度。 2—利用光電計(jì)量管系統(tǒng)克服了蠕動(dòng)泵流量不穩(wěn)定造成的誤差：增加了一個(gè)可視式光電定量裝置，通過(guò)液面遮擋光線引起信號(hào)的改變，精確實(shí)現(xiàn)試劑定量，所以該法克服了軟管磨損降低定量精度的缺點(diǎn)。 3—同時(shí)實(shí)現(xiàn)了微量試劑的精確定量，**減少了試劑使用量。 4—多向選擇閥，通道靈活多樣，摒棄了昂貴的隔膜電磁閥，**降低了維護(hù)量和維護(hù)成本。隔膜電磁閥雖然防腐性能很高，但是對(duì)試劑清潔度卻有較高的要求，試劑不潔時(shí)，經(jīng)常會(huì)出現(xiàn)倒流，并且這類(lèi)電磁閥具有隨其開(kāi)閉而使流體被吸入或排出的泵功能，所以對(duì)于分析取樣的精度提出了更高的要求，尤其是在所取劑量很少的情況下，帶來(lái)的誤差更是嚴(yán)重的。本發(fā)明涉及的選擇閥，與目前市場(chǎng)上水質(zhì)分析儀的電磁閥相比較，具有死體積少，防腐性能高，故障率低，使用壽命長(zhǎng)，易維護(hù)更換等優(yōu)點(diǎn)。 5—試劑進(jìn)樣采用蠕動(dòng)泵負(fù)壓吸入方式，保證液體不和泵管接觸，試劑與軟管間存在一個(gè)空氣緩沖區(qū)，試劑與軟管沒(méi)有直接接觸，所以**降低了軟管的要求并且杜絕了泵管對(duì)液體的污染、避免了泵管腐蝕。浙江優(yōu)良總氮分析儀****</p><p style="text-indent:25px">浙江優(yōu)良總氮分析儀****</p><p
