Explosives Detection Equipment

Description

Thess Model 97 so touringeneration handheld explosives detector designed to be used by security personnel to seqrch people vehicles, podces, and porces for concealed explosives the Mode 97 defects inevopo produced by dwidevoteh of commercia and motory explosivesong provides both on oud be and visuqi indication of gloom

The Mode 97 contains duniquered time detection system not contopidly discrimingle between the vopostom on explosive and those produced by cosmicirnon-explosive rooterio; she results are insion oneous as there is no tedioussomple collection of slow ongos's process in the system. Once on explosive has been detected by the unit it is quomosody purged ceon and is reddy to continue withing few seconds.

Operotion

The Model 97's operation is bosed on twin electron copture detectors (ECD's). Suspect vopor is drown into the instrumentthroughd membrane whichisoloiesitfrom ambi. ent dir. Thevaporisthen mixed with Argon, animericorrier gas, and fed down two columns. One of the columns is coated with a special moteriol which selectively retards the progress of molecules from high explosives. Each of these columns termindfe in CIn ECD.

When the vaporscarrier gas mixture enters the ECD it is bombarded by befo particles from a Sedled radiodctive source (similar to the dmount of radioactivity present in ionization smoke detectors). The befo particles dislodge electrons from the corrier gas molecules which supports the ECD's stonding current. If molecules from high explosives are present they obsorb these free electrons and thus change the standing current and trigger andlorm.

The timing sequence of the signals from the twin ECD's discriminates between vopors from explosives and those produced by similar non explosive substances

iTisearly

The Model 97 because of its instantoneous response ond rugged construction is ided for continuous screening opplications. It con be used, for example, to checksuspect luggoge, pockdges, storoge lockers, qutomobiles, buildings, ond people, etc. Model 97 opplications include Airlines, Nuclear Power Plants, Military Bases, Police Deportments, and Sensitive Government Focilities. The Model 97 is an ideal tool to enhance security of any high risk facility.

Explosives Detection Equipment
ENTRY SCAN MAQk ||

Description

The Entry Scon Moski represents the stole of the dri in explosives detection. # topidly Sedrches personnel for conceded explosives by quickly onglyzing dir sqmples collected from individualsos they enter the instrument's dissiredm. The rapidity and non intrusive noture of the search dssures occeptonce, it is idedly suited for high risk occess control to Nuclear Power Plants, Government Facilities and Defense contractors. The Entry Scan Mark | condlso be integroied with on optional metal detector to protectogdins weapons as well as explosives, The instruments potented detection process provides high sensitivity to explosives coupled with a high degree of immunity to false clarms, The Entry Scon Mork | provides three processing modes to fit dmy opplicotion, in its normal mode it can process up to 600 people per hour which mokes it ided for high troffic entry points. The instrument isotroctively packaged to complement qny decor ond compoctly designed to fit into dreds where spoce is limited.

Operotion

The Entry Scqn Mork | dutomoticolly signals edch person to enter the portal by medns of a green “enter" light. While in the postol, an air somple is collected from around the person being sedrched by medns of d gentle dir curtain. This dir Sqmple is continuously onolyzed in the detection system for the presence of molecules from explosives. The detection mechanism Selectively trops vopor of interest from the sqmple dnd selectively desorbs if into on argon corrier gos stream which corries it into d high sensitivity Electron Copture Detector (ECD). Any molecules from explosives present in the corrier gas mixture will dbsorb electrons in the ECD ond trigger on dudible ond visuddlorm. An oddtional intersoce permits oldsms to be routed to dndlternote location or to ocomputer for logging purposes.

At the completion of the detection cycle the Entry Scon signals the person being Sedrched to exit by medns of d green light dnd on dudible chime. If the individual should leove the instrument before the cycle is completed, on dudible dnd visual dlert Signol will be generosed. When no personnel dre being processed for on extended period of time, the system dutomoticolly switches to Sidndby Mode which conserves orgon gos dnd incredses operational life. When the first person to be processed opproaches the Entry Scon, the system dutomotically returns to the normol operating mode.

The Entry Scon presents simplified controls and indicators to endbleedsy operation dnd monitoring of the system. In dodition, it contains self diognostics dnd indicotors to focilitote Service. A test Gnd colibrosion option is ovdildble which dutomotically tests the Entry Scan of the push of a button and moinfoins the circuitry of optimum sensitivity.
