Product Description
RS PRO 146-4653 digital luminance meter is a reliable and high-precision instrument for measuring light intensity in industrial, laboratory, commercial, and environmental settings. It measures luminance from 9.999cd/m² to 1999 lx, offering a remarkable ±3 accuracy calibrated to the standard incandescent lamp (2856 K at +25°C or +77°F).
The device features a dual display with a 4-digit LCD connected to a high-quality single primary sensor via a flexible long cable, allowing precise measurements in hard-to-reach locations. Its spectral sensitivity closely matches the CIE photopic curve, ensuring measurement accuracy for different lighting types including white LED, fluorescent, metal halide, high-pressure sodium, and incandescent lamps.
The meter supports seven autoranging steps, measuring luminance levels up to 1999k cd/m² and 580.0k footlamberts. It includes extensive functional capabilities such as max, min, average readings, luminance ratio and deviation percentage, color correction, and accumulation luminance measurement. Additional features include a backlit display for low-light environments, data hold, comparator, and a data logger with USB interface for easy export of measurement data.
Designed for durability and portability, the meter is lightweight at 345g, comes in a protective hardcase, and operates in ambient temperatures between 0°C to 50°C. It is perfect for use in warehouses, factories, commercial offices, educational institutions, museums, hospitals, and photography studios.
