CBRN / HazMat training needs to exercise and educate your students. Quite often these days a number of instruments might be used as part of a search or survey. You might for example use a CAM(tm) and an AP2C(tm) for initial assessment, then a Hapsite(tm) to aid confirmation and identification of the substance present. Our technology uses a mix of ultrasound and electromagnetic to simulate the hazard. In this section we provide an overview of each technology. Ultrasound sources are used for long range vapour release simulation, electromagnetic source as used for local contamination simulation and confidence test simulation.
