Nextteq Irritant Tube Smoke Kit

The Nextteq Irritant Tube Smoke Kit is a quick, simple, and economical to use for respirator fit testing and airflow indication. The kits contain everything needed to perform multiple fit tests without the cost of extra equipment. There is no need for chamber construction, nebulizers, electric pumps, mixing jars, batteries, special test masks, mask probes, or testing hoods.

The aspiration bulb pump and Gastec irritant smoke tube is pre-calibrated and ready for immediate use. The tubes require no warm-up time or calibration. Also, there are no special sensitivity test chemical mixtures to prepare in advance.

Irritant smoke is the only OSHA-accepted qualitative fit testing method that does not rely on the test subject’s subjective response. Other types of qualitative fit tests, such as banana oil (Isoamyl acetate), saccharin, or Bitrex, may cause false negative results.

The Nextteq Irritant Smoke Tube Kit for airflow indication is a simple and effective method for tracing and determining the source, direction, and dispersion of air currents. The highly visible white smoke provides an immediate and obvious cue to the directional pattern of air currents.

The kit includes tube caps, enabling you to seal and reuse smoke tubes for added convenience and cost-saving. The Smoke Tubes have an extended shelf life. You can perform fit testing and airflow tracking anytime, and virtually anywhere.

Users can count on accurate readings because Gastec gas sampling pumps, accessories, and detector tubes are designed, manufactured, and calibrated to work together.
