摘要
A portable light and heat blocking rate measurement device/film tester is provided to automatically measure a light and heat blocking rate only by turning on a power switch and immediately confirm the measurement result. A portable light and heat blocking rate measurement device includes a light-emitting circuit(6) and a light-receiving circuit(7) opposite to the light-emitting circuit, measures the quantity of light or heat which passes through a material located between the light-emitting circuit and the light-receiving circuit and displays the measurement data on an LCD(Liquid Crystal Display).
