Features


This Window Tint Meter is a hand held device that measures the amount of light that passes through a window. It measures the total amount of Visual Light Transmission (henceforth

referred to as VLT) through a window and any coatings (tint film) on that window. The device was designed to measure the total VLT of a window after it has been treated with

aftermarket window film. The device slides over a partially rolled down window, does its calculations, and in seconds displays the readings on a LCD . Because it has its own internal

light source, the meter will work day or night.
