· Visible Light Transmittance (VLT)
· Ultraviolet Rejection Rate (URV)
· Infrared Rejection Rate (IRR 940nm, 1400nm)
· Total Infrared Rejection Rate (SIRR)
· Total Solar Energy Rejection Rate (TSER)
· Total Solar Energy Transmittance (SHGC)
· Shading Coefficient (SC)
The Guoou solar film transmission meter offers six measurement modes to meet various measurement scenarios.
The instrument incorporates six intelligent measurement modes, flexibly adapting to the testing needs of different industries and scenarios, including automotive window films, architectural glass films, and sun protection materials, achieving multi-functionality and comprehensive professional coverage.
Core Innovations, Addressing Industry Pain Points
Goo S0 Solar Film Tester Pioneers Electronic Electrostatic Ball Function
Innovation 1: Electronic Plasma Ball Simulation Function
Addressing the significant differences between metallic and non-metallic films in terms of heat insulation principles and market value, the Guoou S0 series solar film transmission meter series innovatively integrates an electronic plasma ball simulation function.
This function can intuitively demonstrate the material differences between metallic and non-metallic films. This provides film application stores with a powerful experiential marketing tool, effectively enhancing professional persuasiveness and customer trust during the sales process.
Guoou S0 series solar film transmission meter Pioneers Intelligent Skin Care Film Function
Innovation 2: Intelligent Skin Care Film Recognition Technology
With the market's increasingly refined demand for UV protection, "skin care films" specifically developed for sensitive individuals have emerged. Guoou has revolutionized the UV light path mechanism, improving UV detection accuracy to the level of one ten-thousandth.
When the instrument detects a window film with a UV blocking rate approaching 100%, the screen will intelligently display a "skin care" label, instantly highlighting the product's core advantages.
