UV transmission Meter
Category：Interior Material Tester
Introduction
Transmittance is an important technical parameter for many optical products, such as glass, solar films, and laminated glass. The testing principle of the transmittance meter is to illuminate the tested material with a visible light source. Sensors detect the intensity of the incident light and the light transmitted through the material, and the ratio of transmitted light intensity to incident light intensity is the transmittance, expressed as a percentage. The transmittance meter adopts a parallel optical path design, suitable for testing thick materials, with an accuracy of up to ±1%. The light source complies with the CIE luminous efficiency function standard, ensuring traceability for metrology institute testing.
Applications
(1) Glass products: automotive windshields, tempered glass, architectural glass.
(2) Solar films: heat-insulating films, tinted films for vehicles and buildings.
(3) Laminated glass: safety glass, tempered laminated glass, decorative laminated panels.
(4) Coated glass: anti-reflective coatings, UV-protective coatings, mirror coatings.
(5) Organic panels: acrylic sheets, polycarbonate panels, transparent plastics.
(6) Quality control & inspection: production lines, material testing, exhibition demonstrations.
Standards
(1) ISO 13468 — Glass and glazing: Determination of total luminous transmittance of transparent materials
(2) ASTM D1003 — Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics
(3) GB/T 2410 — Glass in building — Determination of light transmittance
(4) EN 410 — Glass in building: Determination of luminous and solar characteristics of glazing
(5) JIS R3106 — Determination of light transmittance of glass
