COD測定儀原理詳解

更新時間：2015-07-08點擊次數：3519
COD快速測定儀由COD主機和消解器組成，具有自動控溫、計時、調零、線性回歸、曲線儲存和數據打印等功能。由于測定過程使用強氧化劑，腐蝕性較強，稍有不慎對儀器和氧化劑輸送系統會造成嚴重腐蝕，為此我們采用了的自動氣壓進樣方式進行分析而避免了可能發生的腐蝕現象。儀器可廣泛用于環境保護、科研監測、生產監測等領域，是環境監測與控制的理想儀器。

COD測定儀技術指標：

1、電解電流：10mA、20mA、40mA
2、回流時間：15min（鉻法）
3、水浴時間：30min（錳法）
4、測定范圍：0 mg/L～1000 mg/L
5、系統分析誤差：±5%±0.3 mg/L 與標準化學法相關性優于90%
6、顯　　示：4LED
