Description
Ultraviolet Thief Detection Powder
A discreet fluorescent contact-marking powder designed to help reveal unauthorized handling of protected items, documents, equipment, and other surfaces under ultraviolet light.
Invisible Under Normal Light — Revealed Under UV
Ultraviolet Thief Detection Powder is designed to remain effectively invisible to the naked eye after application. When a treated surface is handled, trace amounts can transfer through contact.
Under ultraviolet light, transferred powder fluoresces visibly, making it useful for authorized loss-prevention, access-control, tamper-detection, training, and demonstration applications.
Invisible Marking
The powder is intended to remain difficult to detect under ordinary lighting, so treated items or surfaces do not appear visibly marked.
UV Fluorescent Detection
Marked surfaces and transferred powder become visibly fluorescent under ultraviolet light, especially in darkness or low-level lighting.
Compact 0.25 oz Container
The quarter-ounce container provides a compact, easy-to-store supply for controlled authorized applications.
Non-Toxic Formula
The source describes the powder as non-toxic. Appropriate handling practices should still be used to avoid unnecessary inhalation, ingestion, or eye contact.
