Molecular formula :
nature : air of harmful substances in the rapid determination of a law. Soaked to the reagent granular silica or ceramic-made indicator installed in about 125 mm long, 7 mm internal diameter of the glassware. Measured air to a certain speed smoked this tubes, the measured material and reagents color reaction occurred, according to the color depth (colorimetric detection tube-type) or change the length of the column (a long-Test Tube), and calibration standards good shade guide or concentration standard of comparison, can be made at the scene qualitative and quantitative determination . The scene is easy to use, fast, easy to carry and sensitive advantages. Some common hazardous substances, such as carbon monoxide, sulfur dioxide, hydrogen sulfide, benzene, mercury and so can detect the pipe to detect.
