New-type explosives detectors have begun to serve at some major stations of the urban rail transport system in Shanghai to help ensure security for the World Expo scheduled for May 1 next year, developers said on Thursday.
The detectors, dubbed SIM 07 and SIM 08, have passed tests by the Ministry of Public Security.
The new products were produced on the basis of the fluorescent polymer sensing technology that was jointly developed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences and Shanghai Sanco Instrument Co., Ltd.
The new detectors are more sensitive than experienced police dogs, and would do no harm to operators and those being investigated and produce no pollutants, according to the developers. |
