Here are some additional links and UV meters I've found, some of the hardware is already specific to test automotive plastic solar films: UltraV: a Portable UV-index Meter UVM30A frequency response curve Solar Films Tester Visible Infrared barrier test instrumentation light solar...

Homework Statement We want to fill a bottle with R-134a. The fluid comes from a fluid line. The bottle is initially empty, the bottle volume is 12 litres, the bottle is insulated (adiabatic filling). The fluid line contains R-134a at 20 bar, saturated steam. Homework Equations Using the...

Ok did the proper tests on my car. It's a Volkswagen Golf 4, and this is the additional hardware that I used: Convoy S2+ Nichia 365nm UV flashlight Arduino Uno reading data from Gsens UVM-30A UV sensor attached. UVM-30A response wavelength: 200nm-370nm The results are as follow: Direct...

Yeah probably it was some anti-IR coating or higher glass thickness, because as far as I know UV does not cause heat, it's the IR mainly. Also, smaller windows or better bodywork insulation or better AC cooling system can lead you to think that. If you mention the make, model and year of both...

Thanks for the link: UV exposure in cars I've found more information online: Assessment of Levels of Ultraviolet A Light Protection in Automobile Windshields and Side Windows UV-A Protection From Auto Glass, Cataracts, and the Ophthalmologist How BMW and Mercedes drivers receive twice as...

I'm curious if car windshields / windows block UV (ultraviolet) light, the one from either the sun, or UV flashlights, like the Convoy S2+ Nichia 365nm.

I'm here to talk electromagnetism related questions.
