Oxygen colorimetric analysis test tube

Oxygen colorimetric analysis test tube

Dolphin Brand DO-HX-12Model Oxygen Test Tube is based upon the principle of 
microanalysis by colorimetry. (color developing agent which gives pink color is reduced 
to color less by a specific technology. This substance reacts with dissolved oxygen in 
the water to turn into a substance with a color which can be compared with a graded 
color comparison tube set which gives the soluable oxygen content of the water). It is 
one of the oil field injected water quality test tube series which is first manufactured by 
the Ministry of Petroleum Industry in our country. It has been used 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, for field operation in testing soluable oxygen content in water. 

Test range: 1.0-12.0ppm 
Production validity: 1 year 
Package: 30 pieces / box 
Storage conditions: room temperature, dark storage 

It needs to be used with standard colorimetric tube for oxygen measurement.
