SRED-I Explosive Detector    
PDF Download
As the current most advanced and sensitive explosive detector, the SRED-I explosive detector was selected to be the highlighted achievement in the new material field in 2010 and entered China Report on Scientific and Technological Development in 2010. It can be used to detect 38 kinds of common explosives including nitro explosives such as TNT and DNT etc. plasticized explosives, emulsion explosives, PW0 explosives and so on and it has the unique advantages in terms of the locally made explosives with the “Asian characteristics”, remedying the defects of products of the same kind in this aspect.
This product has high sensitivity and the lower limit of detection reaches ppq (10-15 g/mL), reaching the internationally advanced level;
The weight is light and the weight of the main engine (including the battery) is only 0.82kg and it can be easily used by one hand;
The continuously operational capacity is strong and it can continuously work for 8 hours after one complete charging;
It has strong adaptability to the environment and it can work normally under the ultra-low temperature condition of -40℃ and extremely wet environment with the humidity of 98%.
Compared with products of the same kind at home and abroad, through integrating the wireless sensing network module, SRED first creates the wireless launch alarm mode and the users can conduct the remote wireless monitoring for the equipment through the computer terminal and Bluetooth headset, effectively guaranteeing the personal life of the font-line staff.


When designing SRED, we started from the actual conditions of the users and integrated the friendly design concept of human-computer interaction and highly sensitive detection technology to make SRED have high level of performance detection and to be more easily operated.
1. Ultrahigh sensitivity
The fluorescent conjugated polymer and mono-molecular layer sensing film- this core technology makes SRED detect the explosive molecule with the weight of quadrillionth gram, which means that its sensitivity has reached the most advanced international level. When the field operation is carried out, it is sufficient for SRED to be equal to the well-trained explosive detection dog.
2. Easy operation
The operation of SRED is very simple and easy and you can master the operation method after the training practice for 3 to 5 hours and put it into the actual application. In addition, the dismountable design makes it much easier to replace the sensing element and battery and no any other dedicated tools are needed for replacement.
3. Light weight
The usability is the core consideration factor during the design process of this product. We use the dedicated mono-molecular fluorescent film, integrate the tailor-made weak optical signal detection circuit and add the light three-proofing molded plastic shell, thus the weight of SRED is only 820g, which is equivalent to the weight of two bottles of standard spring water.
4. SRED-I Explosive detector Performance
Good performance under the low temperature environment;
The locally made explosives can be detected;
Integrate the wireless sensing network module and first create the wireless launch alarm mode.
5. Domestic products of the same kind Performance
The detection is limited under the low temperature environment;
For the locally made explosives in China, the detection speed and sensitivity cannot meet the relevant requirement
6. Detector series based on the ion mobility spectrometry Performance
The equipment is heavy and its operation is complex;
The start-up time is long;
Low sensitivity (10-12);
Have source of radiation.

1. Public Security
Applicable places: security check for the large performance activities at the airport, high-speed rail, passenger terminals, gym and so on
Conditions of the stream of people and logistics: high flow rate
Threat source: personal body and explosives which can be carried with people or those in the registered luggage
Check mode: batch of check, batch of release and conduct the detection using the sampling paper.


2. Checkpoint Ports
Applicable places: frontier checkpoint and customs port
Threat source: explosives which are put in the truck, container and small vehicles.
Check mode: check the vehicles one by one and conduct sampling at the handle, vehicle steering wheel and cargo packing sealing position


3. Deployment in the Important Places
Applicable places: important facilities and places
Threat source: a little of explosives hidden in the electronic instrument, laptop, electric office appliances and so on and explosives hidden in the important places
Check mode: check the room and corners around the important places one by one and the key sampling positions can be centered on the places to which the hands can touch, such as door handle, light switch and so on.

1. Personal detection
SRED is sufficiently sensitive to the vestige of the explosives对which are detected from the human body and its quickness and accuracy make it applicable to the checkpoint and random inspection.
2. Vehicle detection
When the exploder is loaded and transported, the vehicle body will be inevitably polluted by the explosives, thus a large number of explosive molecules will be attached to it. In such case, the pollution is so common that SRED can easily complete sampling and detection even the detection head does not touch it.
3. Detection of the Improvised Exploder
SRED can detect the gas emitted from the improvised exploder and the small size can guarantee that it can be assembled onto the automatic platform which can be operated remotely. And the detection of the bomb producer can guarantee that we can find the improvised exploder at the beginning.
4. Detection of Evidence Obtaining
The high sensitivity of SRED and internal memory provide strong support for its application in terms of forensic pathology. The evidence obtaining personnel can carry out the sampling detection for the vehicle of the suspect or suspicious bomb production device even the suspects themselves and these results can be stored and printed to provide evidence for the investigation of the prosecutor.
5. Cargo Detection
The use of the trace detection technology of gas phase detection can greatly enhance our capacity to detect the hidden explosives, thus SRED can be effectively used to the security check of the cargoes, posts and luggage.
