YT Series Desktop Transmittance Meter

The YT10 Series is a high-precision transmittance meter engineered for fast, accurate measurement of transparent materials. Ideal for glass, films and other clear substrates, it delivers accurate reliable readings in just 0.5 seconds.  Using multiple types of light sources, this instrument can measure visible light at 380nm-760nm and infrared peak wavelength at 940nm (The YT1020 model adds infrared 1400nm, infrared full band, SHGC and TSER). It is equipped with a highly sensitive and responsive silicon photodiode sensor, and is calibrated to ensure measurement speed, accuracy, stability and consistency. The transmittance meter is fast and convenient, and automatically calibrates itself when turned on. The test material can be placed in the slot and test data can be obtained in 0.5 seconds. Widely used in industries such as glass and film production, for measuring parameters such as transmittance and shading coefficient of transparent materials.  Measures Three or Four Light Sources: YT1010 model measures transmittance across ultraviolet, visible (380–760nm), and infrared (940nm) wavelengths.  YT1020 model measures visible light 380nm-760nm; Infrared peak wavelength 940nm, and adds 1400nm, infrared full band allowing for versatile material analysis. Key Features: Exceptional Accuracy Offers a resolution of 0.10% and measurement accuracy within ±1.5% (±1% for standard samples), ensuring consistent and reliable results. Instant Results Delivers measurement data in approximately 0.5 seconds—perfect for production lines, R&D labs and on-site testing. User-Friendly Interface Features a 3.5-inch TFT true-color display for clear, intuitive operation. Broad Measurement Range Supports a wide spectral range and can test samples up to 47mm thick, accommodating both thin and thick transparent materials. Automatic Calibration Calibrates automatically on startup. Just place the sample in the slot and press one button for results. Built to Last Powered via a 5V Type-C connection, with a long-life light source capable of over 3 million measurements and a lifespan of up to 5 years. Note: This item ships direct from the manufacturer. Please allow an additional 3-5 business days for order processing and shipment on all 3nh instruments.
