Inorganic Gas Qualitative Detector Tube (Tube No.131)

General gas detector tubes are designed to measure the concentration of the Measuring Gas with the knowledge of gas components. However, when the measuring gas is unknown, qualitative analysis tubes enable you to analyze the gas quality and know the kind of gases that exist.
Detecting reagents in five layers as shown below change colours as they analyze the gas quality. The existent gas is specified by the colour changes listed in the below table.
