Optical Transmittance Meter with Accuracy Better Than ±1.5% for Glass Films

Introduction:

• The transmittance meter is a domestically produced high-precision handheld transmittance meter designed for quickly and accurately measuring the transmittance of transparent materials. Using three types of light sources, the instrument can measure visible light at 380nm-760nm and infrared peak wavelength at 940nm. It is equipped with a highly sensitive and responsive silicon photodiode as the sensor, and is calibrated with professional algorithms to ensure measurement speed, accuracy, stability, and consistency.
• The transmittance meter is fast and convenient to measure, with automatic calibration when turned on. The test material can be placed in the test slot and test data can be obtained in 0.5 seconds. Widely used in industries such as glass and film, for measuring parameters such as transmittance and shading coefficient of transparent materials.
• Optical transmittance meter is a high-precision optical transmittance meter developed, which is designed for fast and accurate measurement of the transmittance of transparent substances. Three types of light sources are adopted, which can measure visible light from 380nm to 760nm and with a near-infrared source peaked at 940 nm.
• The optical transmittance meter measures quickly and conveniently, automatically calibrates when the machine is turned on, place the sample, and the test data can be obtained in 0.5 seconds. It is widely used in glass, film and other industries for the measurement of parameters such as transmittance and shading coefficient of transparent substances.

Features:

• High precision
• The resolution is as high as 0.10%, and the measurement accuracy is better than ± 1.5% (for colorless and uniformly transparent substances). After testing with a standard sample at the factory, the accuracy can reach ± 1%, ensuring the reliability of the measurement results.
• Multiple light sources
• Equipped with three types of light sources: ultraviolet, visible light, and infrared 940nm, to meet diverse measurement needs and ensure accurate analysis of various transparent substances.
• Quick measurement
• The measurement time is only about 0.5 seconds, greatly improving work efficiency and suitable for fast-paced production and research and development environments.
• Good operating experience
• Adopting a 3.5-inch TFT true color display screen, the large screen operation is intuitive and easy.
• Measuring a wide range of wavelengths
• Covering visible light range of 380nm-760nm and infrared peak wavelength of 940nm, suitable for measuring the optical properties of different materials.
• Ultra thin design, wide sample adaptability
• The sample thickness limit is less than 47mm, which can easily meet the measurement needs of various thicknesses of transparent materials. Whether it is thin or thick samples, they can be accurately measured.
• Automatic calibration
• Automatic calibration upon startup, one click testing, convenient to use.
• Durable and long-lasting
• Powered by a 5V DC power supply (Type-C interface), the lighting source has a lifespan of up to 5 years and supports over 3 million measurements, greatly reducing long-term usage costs.
