Dark Box Triple-Purpose UV Analyzer

The dark box type three-purpose UV analyzer irradiates samples with ultraviolet light, utilizing the different fluorescence or absorption characteristics of substances under 254nm, 365nm UV light, and white light for observation. It is used for identifying components in coatings and inks, detecting defects in plastics and paper, and can reveal internal impurities or coating uniformity issues in materials.
Selection
When selecting, consider the lifespan and wavelength accuracy of the UV lamp. The sample stage size should match the object to be tested. The observation window filter should provide complete protection, and the body structure must ensure the light-tightness of the darkroom. Configure the reflection or transmission lighting mode according to testing needs, and pay attention to power stability and heat dissipation performance.
