The LS183 UV Transmittance Meter is an optical instrument designed to test the transmittance of glass. It contains three light sources that can be used to test the visible light transmittance, infrared transmittance and UV transmittance of coatings, insulating glass, foil glass, PMMA materials, PC materials, etc.

1. Why do we need to test the visible light , UV and IR transmittance?      

Optical performance is very important for materials such as stick-film glass, insulating glass, PMMA, PC. Optical performance commonly refers to the visible light transmittance , UV transmittance , IR transmittance. Only if the visible light transmittance of the glass reach certain standard, will the glass achieve sufficient clarity. The IR transmittance also plays an important role. The glass needs to block the heat from outside. If the IR transmittance does not meed the requirement, it will be very hot inside the room. The glass also need to block the ultraviolet from the outside, so that people won't be tanned. 

2. How does An UV transmittance meter work?

The LS183 UV Transmittance Meter is an optical instrument designed to test the transmittance of glass. It contains three light sources that can be used to test the visible light transmittance, infrared transmittance and UV transmittance of glass. Through these parameters, we can judge the light transmission properties, thermal insulation properties and UV-blocking properties of the glass.

(4)  LS183 UV Transmittance Meter uses a large liquid crystal color display to read data more clearly. The instrument comes with a support frame that can be used either on hand or on a showcase.

(5)  The most important feature is the high cost performance of the instrument, which costs $220.

(6)  This LS183 UV Transmittance Meter is suitable for transmittance testing of coatings, insulating glass, foil glass, PMMA materials, PC materials, etc. 

If you need to measure the visible light transmittance , IR transmittance and UV transmittance,  it is recommended to use LS183 uv transmittance meter for measurement.
