Product Overview
ZK-02 Aluminum Foil Pinhole Tester – designed for pinhole detection in pharmaceutical aluminum foil and other metal foils. Features a specialized observation device for fast and easy pinhole location and sizing. Widely adopted by pharmaceutical companies, aluminum foil manufacturers, and drug control centers.
Test Principle
Under specified environmental conditions and with the light box illumination, the pinholes in the aluminum foil are detected by utilizing their light-transmitting property. Through a dedicated observation device, the number of pinholes is counted and the size of each pinhole is measured.
Key Features & Advantages
- High‑magnification observation: 100× objective lens with 0.1 mm scale division for accurate pinhole sizing.
- Precise pinhole location: 30 W light source and 20–50 Lux ambient illuminance for fast pinhole detection.
- Compliant with standards: Meets the latest YBB pharmaceutical packaging material requirements for aluminum foil pinhole testing.
