Handheld Bomb Scent Detector
The Madoors USA HHED-20 Handheld Explosive Trace Detector is an advanced chemiluminescence technology explosive detection system that detects homemade, military, and commercial explosives — including ICAO taggants, plastic explosives, ammonium nitrate, black powder, other nitrates, TATP, and HMTD — in 2 to 10 seconds from both air vapor sampling and surface wipe testing, without radioactive isotopes or carrier gases. Weighing less than 3.3kg including battery in a 410×140×140mm durable thermoplastic housing, operating on rechargeable battery independently of mains power with 110 to 220VAC AC charging, audible and visual LCD alarm with detected substance identification display, 120,000-record SD card data memory, PC interface for software updates and measurement evaluation, and a working temperature range of -10°C to +60°C, the Madoors USA HHED-20 delivers unsurpassed accuracy, speed, and reliability for detecting the most dangerous and cleverly concealed explosive threats at checkpoints, airports, events, and any security screening position.
TECHNICAL SPECIFICATIONS
The Madoors USA HHED-20 uses advanced chemiluminescence detection technology — the chemical reaction between explosive trace compounds and the detection reagent produces light emission proportional to the concentration of the explosive compound, which is measured by the optical sensor system and processed by the device electronics to confirm explosive identification. Chemiluminescence technology provides the high sensitivity required for trace-level explosive detection from the minute quantities that escape explosive devices through packaging, handling contamination, and vapor pressure.
Analysis time is 2 to 10 seconds from sample introduction to alarm or clear result — the fastest available detection cycle for a handheld trace explosive detector, providing the throughput rate required for security screening of individual passengers, bags, vehicles, and surfaces at high-traffic checkpoints. The 5 to 10-second display of detected explosive type on the integrated color LCD provides the operator with specific substance identification — not just a generic explosive alarm but the specific explosive compound detected.
Both particulate and vapor sampling modes are available — vapor sampling draws air from the sample environment directly into the detector for standoff or close-proximity detection of explosives in the vapor phase, and particulate sampling analyzes swipe samples taken from surfaces where explosive residue may be present from handling or contact. This dual sampling capability allows the HHED-20 to serve both the baggage surface swipe screening protocol and the vehicle and room vapor screening protocol from the same device.
Physical specifications: dimensions 410mm L × 140mm W × 140mm H. Weight less than 3.3kg including battery. Power: 110 to 220VAC 50/60Hz mains charging and 24VDC battery operation — the rechargeable battery provides complete mains-independent portable operation for field deployment. Spare battery is included. Working temperature: -10°C to +60°C.
The SD card slot accepts a 2GB SD card providing 120,000 detection records — each record stores the analysis result, detected substance identification, timestamp, and operator data for the complete audit trail required for security operations documentation and legal evidence management. PC interface provides software update capability and measurement evaluation data transfer to analysis workstations.
KEY FEATURES
2 to 10-Second Detection — Fastest Available Trace Analysis
The 2 to 10-second complete analysis cycle from sample introduction to identified alarm or clear result is the operational speed specification that directly determines the screening throughput of the checkpoint — at 10 seconds per sample, a single HHED-20 operator can screen 6 passengers per minute or 360 per hour in a wipe-test protocol. This rapid analysis enables trace explosive screening at the passenger throughput rates of busy airport, event, and checkpoint security operations without creating unacceptable queue lengths.
Chemiluminescence Technology — No Radioactive Isotopes or Carrier Gases
The chemiluminescence detection principle that requires no radioactive isotopes and no carrier gases eliminates the two most significant regulatory and operational constraints of alternative trace detection technologies — no radiation safety licensing, no radioactive material transport permits, no carrier gas cylinder logistics, and no gas supply interruption risk. This constraint-free operation directly enables deployment of the HHED-20 at any security checkpoint without the specialist regulatory compliance and supply chain management that radioactive source and carrier gas technologies require.
Specific Explosive Substance Identification — LCD Display
The specific detected explosive type identification displayed on the integrated color LCD — rather than a generic explosive present/absent alarm — provides the operator with actionable intelligence for the security response decision. Knowing that ammonium nitrate has been detected indicates a different threat profile from TATP or plastic explosive detection, and the specific identification allows the security response to be matched to the specific threat. This substance-specific display directly improves the quality of the security response at every explosive detection event.
Dual Vapor & Particulate Sampling — Complete Detection Coverage
The dual vapor and particulate sampling capability in a single device eliminates the need for separate vapor detection and surface swipe instruments at the same checkpoint — the HHED-20 serves both the wipe-based baggage and vehicle surface screening protocol and the vapor-based room and vehicle interior screening protocol from the same handheld unit. This dual capability directly reduces the equipment cost and operator training requirement of checkpoint explosive detection.
Rechargeable Battery — Mains-Independent Field Deployment
The rechargeable battery operation with spare battery included provides complete independence from mains power for field deployment — the HHED-20 is operational at any location where no power supply is available, including outdoor checkpoints, vehicle patrol positions, field operations, and any emergency deployment position. The included spare battery directly extends the maximum single-deployment operational duration without requiring return to a charging position.
120,000-Record SD Card Memory — Complete Audit Trail
The 120,000-record SD card storage of all detection events with substance identification, timestamp, and operator data provides the complete audit trail required for security operations accountability, legal evidence documentation, and post-incident investigation. This storage capacity represents months of continuous checkpoint operation records on a single 2GB SD card — providing practical long-term records retention without frequent data management.
Wide Explosive Coverage — Military, Commercial & Homemade
The detection coverage of ICAO taggants, plastic explosives, ammonium nitrate, black powder, other nitrates, TATP, and HMTD covers the complete spectrum of explosive threats from military and commercial standardized explosives through to the homemade explosive compounds — particularly TATP and HMTD — that are the primary concern for improvised explosive device construction in contemporary terrorism. This complete coverage directly addresses the full threat spectrum without the detection gaps that narrower-compound instruments leave.
PC Interface — Software Updates & Data Analysis
The PC interface for software updates and measurement evaluation data transfer provides two critical long-term operational capabilities — software updates keep the detection algorithms and compound identification databases current as new explosive threats are identified, and data transfer to analysis workstations allows systematic review of detection patterns, false alarm rates, and operational performance for security operations management. These capabilities directly maintain the detection performance and operational quality of the HHED-20 throughout its service life.
