Transmission Meter (window Tint Meter)
The AT-173 Transmission Meter is a portable, battery-powered instrument designed for measuring the light transmittance of transparent and translucent parallel-plane samples. Typical test objects include automotive glass, aerospace transparent components, glass products, plastic sheets, and films.
The instrument can also be used to evaluate the turbidity or clarity of liquid samples such as water, beverages, and other transparent liquids.
The measurement principle is based on the ratio of transmitted luminous flux to incident luminous flux through the test sample.
Applications
(1) Automotive industry: window tint films, windshields, side windows, laminated automotive glass.
(2) Aerospace industry: aircraft windows, transparent panels, observation windows.
(3) Glass products: architectural glass, safety glass, coated glass, optical glass.
(4) Plastic materials: plastic sheets, plastic films, acrylic plates, polycarbonate panels.
(5) Liquid samples: water, beverages, and other transparent liquids for turbidity or clarity assessment.
(6) Quality inspection & field testing: production inspection, incoming material testing, exhibitions, on-site measurements.
