Test tube for ferrous (ferrous) colorimetric analysis

Dolphin Brand Fe-HX-10 Model Iron Content Test Tube is based upon the princi ple of Orthoferroin iron content testing by color comparison(Acidized water sample is put into the test tube to react with the color developing agent to become an orange red solution. And it is then compared with a graded standard color to determine the iron content in the water). It is a kind of water quality test tube which is first manufactured by the Ministry of Petroleum Industry in our country. It has been developed by Daqing, Shengli, Zhongyuan,Xinjiang Oil Fields, etc. and is appraised and approved by the users. 

This product has higher quality of sensitivity and accuracy. It is an ideal high-speed instrument which is simple and convenient to operate in testing iron content in water of field. 

Test range: 0-10ppm 
Production validity: 1 year 
Package: 30 pieces / box 
Storage conditions: room temperature, dark storage 

It needs to be used together with the standard colorimetric tube for iron measurement. 

鐵（二價鐵）比色分析試管

海豚牌Fe-HX-10型含鐵量試管是根據比色法測定鐵含量的原理（將酸化水樣放入試管中，與顯色劑反應生成橙紅色溶液）。然后將其與分級標準顏色進行比較，以確定水中的鐵含量）。它是我國石油工業部研制的一種水質檢測管。經大慶、勝利、中原、新疆等油田開發，并經用戶鑒定認可。

該產品具有較高的靈敏度和準確度。它是一種理想的高速儀器，操作簡便，可用于現場水中鐵含量的測定。

測試范圍：0-10ppm

生產有效期：1年

包裝：30支/盒

儲存條件：室溫，避光保存

它需要與標準比色管一起用于鐵的測量。
