Feature:1. MULTIPLE FUNCTIONS: The 3 light sources are combined into one light path, and can obtain transmittance values of visible light, infrared light and ultraviolet light.2. FOR FINE MATERIALS: Can measure ultra small size materials, 1mm test aperture, more accurate and more convenient to measure small material data.3. LCD DISPLAY: The display window adopts a large color LCD screen, and the language can be set to Chinese or English, which is convenient for reading.4. APPLICABLE MATERIALS: Professionally used for optical transmittance testing of lenses, glass, coating materials, organic materials, coatings and other substances.5. HIGH EFFICIENCY: This LCD spectrophotometer has high accuracy and resolution, stable and accurate measurement results, high efficiency and durability.Specification:Item Type: Light Transmittance TesterModel: LS108HMaterial: Sheet MetalApplication: Light transmittance measurementTest Parameters: Ultraviolet: Peak wavelength 365nmVisible Light: 380nm-760nm full wavelength (in line with CIE photopic vision function standard)Infrared: Peak wavelength 940nmMeasurement Accuracy: ±2% (colorless and uniform light transmitting material, 0-90% transmittance)Minimum Test Object Size: 1mm diameterSample Maximum Thickness: Approx. <20mm / 0.8inResolution: 0.1%Power Input: DC5V/1A (Type-C interface)Language Setting: Chinese and EnglishScope of Application: Optical transmittance test of various substances such as lenses, glass, coating materials, organic materials, coatings, etc..Package List:1 x Light Transmittance Tester1 x Data Cable1 x User ManualNote:1. The instrument is self‑testing and self calibrating when it is turned on. No test objects can be placed in the test position, otherwise the self calibration cannot be completed.2. Avoid contact with corrosive items and keep away from high temperature and high humidity environment.3. When there is no test object, the transmittance data cannot be returned to 100% occasionally, and the instrument can be used normally after shutting down and restarting immediately without affecting the measurement accuracy.4. When the instrument is not in use, please turn off the power.5. When the interface is abnormal voltage interface, please replace the power supply
