Gas Detector Tubes

A quick evaluation of the potential danger resulting from fires, accidents and other disasters is achieved with the Action Detector Tubes. A special calibration permits the use of most of the Action tubes with only two pump strokes. To ensure a fast and simple reading only two warning markings are printed on the Action Tubes. A third mark “ETW” is newly printed on the Action tubes. ETW means “Einsatztoleranzwert” according to the German guide-line vfdb 1001 [0303]. The guide-line is published by “Vereinigung zur Förderung des Deutschen Brandschutzes e.V.” In case of concentration above ETW for more than 4 hours respiratory protective devices are required. ETW are established for 33 substances.
