TA630 Series High Accuracy Digital Lux Meter (Illuminance Meter / Light Meter / Light Measurement Instrument) is a professional optical measurement instrument designed for accurate illuminance testing in various environments, including industrial lighting inspection, architectural lighting evaluation, laboratory light analysis, and daily illumination measurement applications. The series adopts a high-sensitivity silicon photodiode sensor with optical filter technology, providing a spectral response range of 400～700nm that closely matches human visible light perception. It delivers stable and accurate illuminance measurements for different types of light sources and application environments. The TA630 series includes two models: the TA630A Integrated Digital Lux Meter and the TA630B Remote Sensor Digital Lux Meter. With a wide measurement range of 0.1～200000Lux / 0.01～20000FC, automatic range selection, and high measurement accuracy, it can meet the requirements of both low-light environments and high-intensity industrial lighting inspections. Combining the functions of a lux meter, illuminance meter, light intensity tester, environmental light meter, and illumination measurement device, the instrument supports Lux/FC unit conversion, data hold, maximum/minimum value recording, backlight display, and auto power-off functions. Its compact handheld design allows engineers and technicians to perform fast and convenient on-site measurements. The TA630 Series Digital Lux Meter is widely used in industrial manufacturing, smart factories, building lighting projects, office and commercial lighting evaluation, schools, laboratories, hospitals, warehouses, photography studios, museums, greenhouse agriculture, and retail environments. It is an ideal solution for lighting acceptance testing, workplace illumination inspection, energy-saving lighting upgrades, and overall light quality management.
