Colormetric Gas Sampling Tube |
Glass tubes through which a gas sample is drawn to allow the user to measure various types of gas found in the atmosphere. The tubes contain reagents that filter or bond to non-target gases and reagents that change hue when they come in contact with their target gas. The concentration is given by the length of the color change, as indicated by a printed scale on the outside of the glass tube.
