(1) double advantages: measuring gas detection tube is actually a chemical quantitative analysis method. It is a quantitative, qualitative and quantitative detection method. It has the double advantages of chemical analysis and instrumental analysis.
(2) good adaptability: there are three kinds of detection tubes, i. e., I, II and III, ranging from zero point to several PPM (10-6) to 10%, which is very suitable for analysis.
(3) the operation is simple and convenient: it provides a great convenience for the professional inspectors, and the operator can do the test according to the operation method of the instruction manual.
(4) use safety: manual operation in use, no need for power, heat source, in the presence of inflammable and explosive gas can be used safely.
(5) the analysis speed is fast. Because of the convenience of operation, the time needed for each analysis is greatly shortened. Generally, it can be known only in ten minutes, and its analysis speed is no match for any chemical analysis or instrument method.
(6) the measurement accuracy is high. The field analysis condition is simulated on the determination of the content scale of the detection tube. The calibration method with different standard gases overcomes the error in the chemical analysis. At the same time, human error is reduced.
It is mainly used to check the content of various gases in the air. Combined with gas detection tube.
1, with the sand slices, a little force will be used to cut the two ends of the test tube.
2. A silicone tube sleeve is used to hold one end of the arrow on the test tube, break off along the cutting seal and break the other end with the same method.
3, use the silicone tube sleeve to hold the end of the arrow on the test tube (prevent air leakage), insert the gas channel mouth which is to be detected. Pay attention to the direction, the arrow direction is the direction of the gas flow.
4, the testing tube of several items needed to be detected, after all the above methods are inserted, the power supply can be used normally.
5, adjust the time controller corresponding to the required detection gas, so that it meets the technical index (see the attached table).
6, the detection end, pull out the detection tube.
7, the handheld detection tube is downward and vertical to the ground. It is placed in the position with a basically uneven eye. The color change scale on the tube is observed, which is both the concentration of the detected gas.
