1. Product introduction:
It is mainly used for the display of latent sweat marks on non-permeable objects, especially for the display of difficult fingerprints in folded and crumpled samples (such as tapes, plastic bags). In a vacuum state, water molecules and vaporized 502 molecules diffuse freely, and the fingerprint lines are more uniform; in a vacuum state, the reaction of 502 glue with fingerprints is more sensitive, and the fingerprint lines are clearer; in a vacuum state, the background of fingerprints is cleaner.
2. Product advantages:
1. Using 7" color LCD touch screen, Chinese display and operation interface, one-finger touch, intelligent, intuitive and fast;
2. Use automatic smoke display/manual smoke display and smoke display parameter self-modifiable mode;
3. The use of advanced technology of stainless steel rectangular vacuum fumigation cavity to maximize the effective space, and the placement of inspection materials is barrier-free;
4. Adopting the original movable door flexible closed structure design, which not only ensures the overall sealing performance, but also improves the service life of the sealing ring;
5. The detachable cabinet door sealing ring design is adopted to avoid the trouble of user replacement;
6. The large size observation window of laminated bulletproof glass is adopted, which is safe, reliable and high in observation;
7. The use of a high-power and low-noise 2-stage vacuum pump can shorten the operation time for vacuuming large spaces;
8. The external vacuum pump refueling/unloading device is designed to avoid the inconvenience of replacing the vacuum pump oil;
9. Adopting internal circulation air filter device design to improve the safety of operators;
10. Built-in LED double-side lighting device, the smoke display effect is observed more clearly;
11. Built-in humidification/smoke display heating device, which can complete the humidification and smoke display functions under the intelligent control of the microcomputer;
12. There is an emergency relief valve for power failure to ensure the safety of inspection materials;
13. Using QR code technology, use mobile phone WeChat to directly read equipment instructions and troubleshooting;
14. There are network and USB sockets for running program software upgrades and data output;
15. Adopting the designed integrated structure of desktop pump and machine, the cabinet is beautiful and practical.
