Introduction * Solar Film Transmission Meter is able to simultaneously measure and display UV, IR rejection value and visible light transmission value. * This meter is self-contained light sources and self-calibration. No manual adjustment is needed. It is suitable for the transmittance (barrier ratio) test of automotive film, architectural film, thermal film, film glass, etc. * The users only need plug the power supply, turn on the switch and put the solar film in the opening. The resulting performance data appear on the display. Technical Specifications * Size: 160mm*115mm*33mm(L*W*H) * Testing opening: Wide 23mm * Height 76 mm * Weigh: 425g * Resolution: 0.1% * Accuracy: +/-2%(Colorless and transparent material) * UV Peak wavelength: 365nm * VL Peak 380-760nm, conforming to the CIE photopic vision function standard * IR Peak wavelength: 940nm *4*AA alkaline battery（Battery Not Included In the Package） Features * UV Rejection meter, IR Rejection meter, Light Transmittance Meter, Three function in ONE device. * Self-calibration and auto-calibration, NO need any manual adjustments * Simple operation, putting the testing sample in the opening, UV Rejection, IR Rejection, Visible light transmission value of the sample will simultaneously display.
