The oxygen dioxide detection tube is suitable for detecting the oxygen content in the air of coal mine, environmental protection, paper industry and so on.
The detection tube can be quickly detected without any energy or power supply, and has the advantages of simple operation.
It is easy to carry and can detect the oxygen content in the air.
Working Principle of Gas Detection Tube
All kinds of gas detection tubes are made by filling a certain amount of detective agent (i.e. indicator powder) in a fixed glass tube with limited length and inner diameter, fixing it with plug, and sealing the two ends of the glass tube. Detecting agent is a kind of substance which can react with the substance to be tested and can change the color of the chemical reagent adsorbed on the surface of solid carrier particles. The choice of chemical reagent and its chemical concentration ratio on the carrier determine the composition and range of the substance in the detection tube.
Application of Gas Detection Tube
All kinds of calibration pipes can be used with CZY-50 gas calibration pipes, such as cylindrical positive pressure sampler.
According to the direction of air intake on the test tube, first cut the upper end of the test tube, then cut the zero end, quickly connect the zero end with the sampler which sampled 50 milliliters, and pass through the test tube in 100 seconds at an average speed, then read the data at the upper end of the brown column.
Measurement range: (1-21)%
Note: The longer gas detection tube can be customized according to the user's needs.
