Laser Labs has developed an extremely accurate Tint Meter for measuring tinted windows which do not roll down. The Tint Meter Model 400 has a two-piece design which allows you to sandwich the glass you are testing. The Model 400 can measure material as thin as a sheet of window film on up to ½ inch thick glass. Tint Meter Model 400 utilizes a magnet alignment mechanism
and auto-calibration for consistently accurate readings. For hard to reach areas, suction cups adhere the light source to the inside of the window. The Model 400 is not affected by ambient light, and performs as accurately in the day as it does at night. Two (2) nine volt (9V) batteries are all that is required.
Each Model 400 Is equipped with two (2) N.I.S.T. traceable reference samples to verify the meter’s accuracy.
