Hach 創新螢光法 LDO® 感測器技術,讓您精準有效輕鬆完成溶氧測量!

溶氧的測量對於污水處理產業非常重要,因為污水廠的曝氣,硝化反硝化,以及達標排放等過程都和溶氧數值息息相關。透過準確的溶氧讀數來精確控制曝氣量能夠大幅降低污水廠的維運成本。在2003年之前,人們還只能使用膜法技術測量溶氧,但是膜法電極維護量大,維護成本高,讀值不穩定,因此業內很多企業都在尋求新的解決方案。2003年,Hach發明螢光法測溶氧,引領了業界解決方案。此領先技術後來也被美國EPA作為NPDES (National Pollutant Discharge Elimination System)報告溶氧的標準方法之一。

•No Calibration Required
•No Membranes to Replace
•No Missed Cleaning Cycles

客戶使用見證
美國Hach公司革命性螢光法測溶氧傳感器LDO系列擁有精準讀數和可靠品質,無需校正,無需換膜,日常維護量極低,這些特性大幅提升測量效率,因此也迅速改變傳統測量方式。
 
Hach的革命性螢光法技術是在LDO傳感器的最前端罩上覆蓋一層熒光物質,LED光源發出的藍光照射到螢光物質上,螢光物質被激發並發出紅光;一個光電池檢測螢光物質從發射紅光到回到基態所需要的時間。這個時間只和藍光的發射時間以及氧氣的多少有關。傳感器另有一LED 光源,在藍光發射的同時發射紅光,做為藍光發射時間的參考。傳感器周圍的氧氣越多,螢光物質發射紅光的時間就越短,據此計算出溶氧的濃度。
  1. 無需校正: Hach LDO® 傳感器開箱即用,無需校正,螢光帽使用壽命長達兩年。
  2. 無需更換膜片: 有了Hach突破性的螢光技術後,傳感器無需基本維護,因為已無需更換膜片,也不用補充電解質溶液,更無需對陽極和陰極進行打磨清潔。
  3. 服務無漏失 : 可自訂清潔服務提示,到時自動觸發服務提示消息,這樣就絕不會錯過傳感器清潔週期。
  4. 無漂移 : 劃時代的3D校正技術,使得Hach LDO® 傳感器在出廠前完成精正校正,測量比以往任何時候都更準確!
  5. 更堅固 : 創新的Hach LDO® 殼體在採用新材料的同時進行O型圈和超音波雙重密封,提高耐用性,同時縮小尺寸,使得操作更容易。
Hach’s next generation LDO (Luminescent Dissolved Oxygen) Probe requires no calibration for the entire 2 year life of the sensor cap, which means it is ready to start measuring your DO (Dissolved Oxygen) right out of the box. With an added cutting-edge 3D calibration procedure that is conducted prior to shipping, the probe will not drift and is more accurate than ever before.
 
By utilizing Hach’s breakthrough luminescent technology for measuring DO, this optical probe has no membranes which need to be replaced or electrolyte solution to replenish, making it virtually maintenance free. 
 
To make sure routine cleaning cycles are never missed, the probe offers operators customizable diagnostic alert indicators, ensuring the probe can operate at its maximum performance level. An improved body design optimizes the probe’s temperature sensor to provide an even faster response time to process variability as well. The probe comes with a three year warranty, and the sensor cap has a two year warranty.
 
So for supremely accurate DO measurements by a probe that does not require calibration and is membrane free, turn to an innovator in DO technology, and Hach’s next generation LDO Optical Dissolved Oxygen Probe.
 
PROGNOSYS is a predictive diagnostic system that allows you to be proactive in your maintenance, by alerting you to upcoming instrument issues. Know with confidence whether changes in your measurements are due to changes in your instrument or your water.
