Professional Digital Lux Meter
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 worlModel | TA632A | TA632B | |
