GUOOU S0 ProMax Portable Solar Film Transmission Meter with UVR/IRR/VLT/TSER/SIRR/SHGC/SC Parameters with 2.01 Inches Color Screen

S0 series optical solar film transmission meter

Solar film transmittance meter adopts
parallel light path design which is very suitable for optical properties testing of automotive films, explosion-proof films,
architectural films, thermal insulation films. It can measure UVR,IRR,VLT at the same time ,and S0 ProMax model also can measure SHGC,TSER,SIRR,SC.
The large-screen HD color screen display and deepened test slot,easy to use it.

The entire S0 series comes standard with two innovative functions: 1. Skincare film detection; 2. Electronic plasma ball for metal film identification. Showing the true value of every film.

GUOOU S0 Transmission Meter

portable transmission meter is a classic three-band solar film tester. Three test holes are used to test the visible light
transmittance, UV rejection rate and infrared rejection rate of the material. Simply place the tested material in the test slot
then we can read the three test data at the same time. It is mainly suitable for optical properties of various uniform and
transparent materials such as solar film, laminated glass and automobile side glass.

GUOOU S0promax Optical Transmission Meter

can measure eight parameters,including:UV rejection rate,visible light transmittance, infrared 950nm and infrared 1400nm rejection rates, all infrared rejection rate, SHGC , TSER, SC.

Other instruments can only measure three of these parameters,so there is a difference in price.Many customers will find it difficult to choose a three-band window tint meter,
because the solar film rejection is different when measuring with different infrared light sources. But if you use this
instrument,there is no such confusion,you can choose the middle gear to read the average of the two infrared rejection rates.

1. how can we guarantee quality? Always a pre-production sample before mass production; Always final Inspection before shipment. 2. What about production lead time? Sample order takes about 1-3 days. for bulk order it takes about 7-15 days. 3. Can I brand this product with my logo? Yes, we can offer many kinds of branding service, such as screen printing, laser carving,embossing & debossing. 4.Can I request 1 or 2 sample for testing the quality? Yes, we are pleased to send you samples to test the quality. support mixed samples. 5. What is the use of testing TSER? How to calculate TSER? TSER (Total Solar Energy Rejection) represents how much solar heat the window film can block. TSER is not a single metric but a composite of three factors: (IRR × 53%) + (VLT × 44%) + (UVR × 3%). Each element plays a role: IRR — Infrared Rejection (controls heat) VLT — Visible Light Transmission (affects clarity) UVR — Ultraviolet Rejection (sun protection). TSER serves as a crucial reference value for ilm selection, but achieving a balance between heat rejection, light transmission, and protection is equally vital—this equilibrium ultimately determines the film's real-world performance.
