VexTrace is efficient both indoors and outdoors at temperatures above zero

VexTrace can detect and identify a wide variety of explosives including pure explosives and composite explosives under different humidity and pressure conditions in vapour* and trace (particles) modes.

The list of explosives includes: TNT,RDX,C4,Semtex,PETN,ANFO,EGDN,Nitroglycerine (NG), Dynamite, DNT, Black Powder , Ammonia and Urea nitrates, HMTD, Tetryl, HMX, PICRIC ACID and mixtures thereof.

The cost of ownership of VexTrace is very low, as no special consumables are required. Regular aluminium foil wipes are used for sampling in the trace mode.

VexTrace runs on the Field Asymmetric Ion Mobility Spectrometry principle. VexTrace contains no radiation sources. Corona discharge functions as the source of ionization.

VexTrace features user authorization function with the internal memory which allows to save more than 5OO K results of analysis.

  • no special calibration required
  • warms up in only 30 sec
  • easy to use, no special training required

Presence of an explosive is visualized on the LCD display of the device or any Wi-Fi device usable as a remote control.

GPS option allows to determine the coordinates of the device when an alarm is detected and save the information to the database.

Optional built-in searching radiometer in intended for measuring g-ray dosage. It allows fast and effective detection of radiation sources with extra short exposure time.
