Rapid Gas Detection Tube
The rapid gas detection tube is the simplest gas detection device. It has the advantages of simplicity, high accuracy and the ability to accurately detect the type of gas to test. However, the downside is that it is only disposable with each tube. For applications that need to measure a variety of gases and do not need to be measured many times, this is a great option.
Fast gas detection pipe principle
The gas to be measured passes through the tube, the chemical reaction will change the color of the tube. Rely on the printed line on the tube to know the gas concentration to be measured. As with the principle of measurement in general, we need a concentration to choose the right pipe.
Basic configuration:
- Hand pump or electric pump: To suck air through the gas detection tube
- Rapid gas detection tube: Each type is used for 1 different gas
- Accessories: Clamps, pipe breaker, straws … depending on the manufacturer
