The TA632 Series is a professional Digital Lux Meter, also known as an Illuminance Meter, Light Meter, Lux Measurement Instrument, or Photometric Testing Device, designed for accurate visible light measurement and lighting environment evaluation. Equipped with a high-precision silicon photodiode sensor with optical filter technology, the instrument provides excellent spectral response characteristics close to human vision, covering the 400–700nm visible light range. It delivers fast and stable illuminance measurement with support for both Lux (lx) and Foot-Candle (FC) units, meeting different lighting measurement requirements worldwide. The TA632 Series integrates advanced measurement functions including data hold, maximum/minimum recording, average value calculation, delayed measurement mode, high/low illuminance alarm settings, and customized light source correction coefficients. These features make it suitable for professional lighting inspection, engineering acceptance, environmental assessment, and laboratory optical testing. The TA632B model is equipped with USB communication capability, allowing connection to a computer for real-time data acquisition, historical data storage, measurement curve generation, and test report management. It is especially suitable for quality control, compliance inspection, long-term monitoring, and professional measurement applications. With a portable handheld design, wide measurement range, and reliable performance, the TA632 Series Digital Lux Meter is widely used in architectural lighting, commercial buildings, schools, hospitals, industrial manufacturing, photography studios, agricultural lighting, laboratories, and third-party inspection services, providing engineers, lighting designers, and quality professionals with an efficient solution for illuminance measurement and lighting evaluation.
