  • Gas Detector Tube System

  • The Kitagawa Gas Detector Tube system is a complete sampling and analysis system for determining the concentration of hazardous gases and vapors on the spot. 

    Kitagawa America offers more than 300 types of detector tubes to detect a wide range of gases and vapors, in a multitude of concentration ranges from ppb to percent. Tubes are calibrated on a single pump stroke, and provide a direct reading of the gas concentration. Each detector tube is wrapped in a thin transparent film that guards against shattering of the glass tube and the dispersing of chemical reagent in the event of accidental breakage.

    The AP-20 piston-type sampling pump accurately and reproducibly draws a 100cc sample through the detector tube. Its molded contoured grip makes sampling easy. A single stroke is all that is needed. A Sample Finish Indicator provides a positive visual indication that sampling is complete and the detector tube is ready to be read. Its integral detector tube tip cutter retains the glass shards and allows for their ultimate safe disposal.
