<div>　　<a href="http://www.tianhualian.com.cn/Products-24147465.html" target="_blank">工業(yè)濁度儀</a>是測定水濁度的裝置。有散射光式、透射光式和透射散射光式等，統稱(chēng)光學(xué)式濁度儀。其原理為，當光線(xiàn)照射到液面上，入射光強、透射光強、散射光強相互之間比值和水樣濁度之間存在一定的相關(guān)關(guān)系，通過(guò)測定透射光強、散射光強和入射光強或透射光強與散射光強的比值來(lái)測定水樣的濁度。光學(xué)式濁度儀有用于實(shí)驗室的，也有用于現場(chǎng)進(jìn)行自動(dòng)連續測定的。<br /> </div><div>　　工業(yè)濁度儀在使用中由于各種原因會(huì )出現一些故障或讀數出現誤差，下面就來(lái)為大家介紹一下工業(yè)濁度儀常見(jiàn)的幾個(gè)故障。<br /> </div><div>　　1、電源燈不亮：濁度儀的電源燈不亮可能是因為和電源的接觸不良，這個(gè)問(wèn)題只要檢查插頭、插座后，重新安裝電源即可解決。濁度儀電源燈不亮的另一個(gè)原因是濁度儀內部的保險絲熔斷，這就需要使用者為濁度儀更換新的保險絲。<br /> </div><p align="center"><img src="https://img70.chem17.com/9/20221201/638055112270235717194.jpg" alt="工業(yè)濁度儀" width="468" height="500" align="middle" /></p><p> </p><div>　　2、重現性低：濁度儀的重現性低除了樣杯本身的故障原因之外，還存在其他兩種可能性，種是濁度儀所使用的樣杯放置位置變化，另一個(gè)是樣杯中液體取量差異過(guò)大。濁度儀在測量時(shí)，使用者可以通過(guò)準確放置樣杯和保持樣杯內液量水平來(lái)避免這一問(wèn)題。<br /> </div><div>　　3、讀數不穩定：濁度儀的讀數不穩定并不一定是濁度儀本身的原因造成的，操作上的失當也會(huì )導致濁度儀的讀數不穩定。濁度儀所測量的液體中存在有較多氣泡時(shí)，濁度儀的測量數值就會(huì )受到影響，因此濁度儀的測量必須等待水溶液樣品中氣泡散去后才能進(jìn)行。<br /> </div><div>　　濁度儀讀數不穩定的另一個(gè)原因則是水溶液在倒入樣杯時(shí)出現了掛杯，也就是在樣杯的杯室內有液滴或樣杯的外壁有水珠，這樣光線(xiàn)的散射受到了干擾，工濁度儀就無(wú)法獲得準確的測量結果，避免的方法是在測量前將濁度儀的樣杯用濾紙擦干。<br /> </div><div>　　4、誤差大：濁度儀的誤差大可能是因為之前所標定的曲線(xiàn)出現了較大的誤差，這就要使用者對濁度儀進(jìn)行重新的校準和標定。另外，濁度儀測量的溶液溫度較高，在樣杯上產(chǎn)生了水霧，也會(huì )使得濁度儀的測量結果出現較大誤差。</div> </div> <div id="9ndoe5t" class="ly_PrevNext"> <ul>
