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. 

铁（二价铁）比色分析试管

海豚牌Fe-HX-10型含铁量试管是根据比色法测定铁含量的原理（将酸化水样放入试管中，与显色剂反应生成橙红色溶液）。然后将其与分级标准颜色进行比较，以确定水中的铁含量）。它是我国石油工业部研制的一种水质检测管。经大庆、胜利、中原、新疆等油田开发，并经用户鉴定认可。
