86182 Solar Film Transmission Meter
SHGC: Solar Heat Gain Coefficient
UV Peak Wavelength: 365nm
Visible Light Range: 380–760nm
IR Wavelengths: 940nm, 1400nm, and Full IR
The 86182 Spectrum Transmission Meter is designed to measure SHGC (Solar Heat Gain Coefficient), which represents the total solar transmittance. It also evaluates the rejection rates for infrared wavelengths at 940nm, 1400nm, and full-spectrum IR, the ultraviolet (UV) rejection at 365nm, and visible light transmittance from 380nm to 760nm.
The device operates by projecting ultraviolet, visible, and infrared light onto transparent materials. Sensors measure both the original light intensity and the transmitted light. The ratio between them, expressed as a percentage, indicates the material's transmittance. For most solar films, visible light is rated by transmittance, while infrared and UV rays are assessed by rejection rate.
The rejection rate = 100% - transmittance
Application
The 86182 meter is highly versatile thanks to its parallel light path design and wide test slot. It is ideal for measuring solar films, laminated glass, and other thick or multi-layered materials. This instrument is well-suited for use in product exhibitions, manufacturing, quality control, and inspection of solar films.

FAQ
-
1. Why is 86182 so expensive and what advantages does it have compared to other window film transmission meters?
86182 can measure six parameters: UV rejection rate, visible light transmittance, infrared 940nm and infrared 1400nm rejection rate, full infrared rejection rate and SHGC. Other instruments can only measure three of these parameters, so there is a difference in price;
SHGC is the total transmittance of solar energy, through which the SC shading coefficient can be calculated;
86182 uses a large color LCD screen, which can switch between graphic display and percentage data, making the reading more intuitive.
