LS181 solar film tester testing principle is to use ultraviolet light, visible light and infrared light radiation measured transparent material, sensor detection respectively three light source of the incident light intensity and light intensity through the transparent material after being tested, through the ratio of light intensity and the incident light intensity is the transmittance, expressed in percentage. Most of the solar film, index of mark visible light transmittance, infrared and ultraviolet blocking rate, blocking rate = 100% - transmittance.LS181 direct measurement and display of uv blocking rate, infrared blocking rate and visible light transmittance, convenient for reading and understanding.
1. The overall dimensions: length 216 mm x 134 mm x 29 mm wide 2. Test slot size: 47 mm wide x 91 mm deep 3. The instrument weight: about 590 grams 4. Resolution: 0.1% 5. Accuracy: better than + / - 2% (colorless uniform pervious to light material), the factory model standards for testing is better than that of plus or minus 1% 6. Uv: peak wavelength of 365 nm 7. The visible: the peak wavelength of 550 nm 8. Infrared: the peak wavelength of 950 nm 9.5 V AC/DC power supply, also can use mobile power supply (optional)( Standard accessories without mobile power supply)
. Uv blocking rate, the infrared blocking rate, visible light transmittance instrument (transmittance) triad; 2. Parallel optical path design, the test data are not affected by the influence of the test sample is placed; 3. Suitable for automotive film, explosion-proof membrane, membrane architecture, insulation film, film, such as glass, the transmittance of (cut off) testing; 4. The instrument has the function of real-time dynamic auto-calibration, after startup automatic calibration; 5. The operation is simple, quickly, only will be tested in a test tank, immediately shows three test results at the same time; 6. Suitable for solar film performance show exhibition, production, quality inspection, inspection and other occasions;
