Pinhole Tester

The pinhole tester for aluminum foil is a device specifically used to detect micro - pinholes in aluminum foil materials. The following is a detailed description of its main uses, compliance standards, and technical parameters:

I. Main Uses

The pinhole tester for aluminum foil plays a crucial role in the quality control of aluminum foil and its composite materials. As a material widely used in packaging, construction, electronics, and other fields, the size of the pinholes in aluminum foil directly affects its moisture - proof, gas - barrier, and light - shielding properties. Especially in the production of pharmaceutical aluminum foil, the detection of pinhole size is a key step related to the airtightness of pharmaceutical packaging and the quality of drugs. If there are dense, continuous, and periodic pinholes in the aluminum foil, it will increase the permeability of gases such as oxygen and water vapor through the aluminum foil, thereby affecting its moisture - proof performance and leading to the deterioration of drugs. Therefore, using a pinhole tester for aluminum foil to conduct strict pinhole detection on aluminum foil is an important means to ensure the quality of aluminum foil.

II. Compliance Standards

- YBB00152002 - 2015 Pharmaceutical Aluminum Foil - GB/T 3198 - 2010 Aluminum and Aluminum Alloy Foil - GB/T 22638.2 - 2008 Test Methods for Aluminum Foil

III. Technical Parameters

- Observation Size: Generally 400mm×250mm, and this size can cover the testing needs of most aluminum foil samples. - Transmitted Light Illuminance: Usually 1000Lux, ensuring that the pinholes on the aluminum foil can be clearly observed during the testing process. - Ambient Light Illuminance for Application: Generally between 20Lux and 50Lux to adapt to the needs of different testing environments. - Magnification Graduation Value: 0.1mm, enabling precise measurement of the size of pinholes. - Objective Lens Magnification: Usually 10X×10X, that is, 100 - fold magnification, making the details of pinholes more clearly visible. - Minimum Measuring Grid Value: 0.01mm, capable of detecting tiny pinholes. - External Dimensions: Generally 800mm (length) × 600mm (width) × 300mm (height), facilitating placement and movement. - Net Weight: Usually about 20kg, with a compact and stable structure.
