1.One of the most important characteristics of Laminated Glass with EVA(Ethylene-vinyl acetate) Interlayer Film or PVB(Polyvinyl butyral) Interlayer Film is UV radiations blocked. Due to this characteristic, the Laminated Glass with EVA Film or PVB film can protect the goods and people inside the room from the UV radiations.
So you may ask how to measure the UV Blocked Rate of Laminated Glass with EVA Interlayer Film or PVB Interlayer Film.
You can use the following light meter to measure the UV Blocked Rate.
Laminated Glass Spectrometer
User Manual V1.6
1: General description
LS Laminated Glass Spectrometer is able to simultaneously measure the Transmission
Values of UV(ultraviolet radiation), Visible Light and Infrared Ray . The Spectrometer is self-contained light sources and automatic calibration. No man-driven adjustment is needed. The users only need to plug the power supply, turn on the switch and put the Laminated Glass in the opening. Then the measure data would appear on the display automatically.
–Testing opening size: Wide 23mm × Height 76 mm
–Resolution ratio: IR, VL is 1%; UV is 0.5%
–Infrared peak responsive wavelength is 950nm, range (850nm-1050nm)
–AC/DC power supply 9V, portable Lithium rechargeable battery also can be used.
–Plug the power supply,
-Keep the opening is empty,
-Turn on the switch,
-Waits for the meter to self-calibrate, if automatic calibration is successful, each of the displays will show 100%.
-Put the laminated Glass in the opening,
-Wait for the data being stable, then read the data
