Range Glass Plastic Visual Light Transmission 18mm Thickness Continuous Measuring Digital Window Tint Meter With Sensor With Automatic Calibration

1. This Window Tint Meter is a hand held device that measures the amount of light that passes through a window 2. It measures the total amount of Visual Light Transmission (VLT) through a window and any coating (tint film) on that window 3. This is designed to measure the total VLT of a window after it has been treated with after market window film 4. The device slides over a partially rolled down window, does its calculations, and in seconds displays the readings on the LCD 5. Additional features includes continous measuring mode and it has its own internal light source, so the meter will work day or night
