The Draeger Safety Clandestine Lab Simultest Kit is a quick and simple method for detecting toxic chemicals. It is based on a five-tube set designed to detect gases present in a clandestine lab. The semi-quantitive test takes four minutes to provide on-the-spot results. Since there is no power source required and the tubes are pre-calibrated, the Clandestine Lab Simultest Kit is always ready for use. A laminated full-color instruction card is supplied with the kit to provide a quick reference on the simple sampling procedures and accurate interpretation of results.
