PCE-LED 1 Light Meter light meter to test LEDs / measurement range from 0.05 to 7000 lumens / automatic change of the range in 4 levels / large LCD display with 5 digits for 38,000 values / software and data cable for data analysis included
The PCE-LED 1 light meter is used to check LEDs via an external sensor. With the PCE-LED 1 light meter you will be able to perform single or series measurements with a predetermined reference value. The measured values can be automatically or manually stored in the internal memory of the PCE-LED 1 light meter to be transferred to a PC or laptop. The software and data cable are included in the delivery. The adapted plaques allow you to check LEDs with a diameter between 2 and 24 mm. LEDs cannot be produced with constant optical properties due to their manufacturing process. Even within the same production series, LEDs can be different regarding to the brightness and colour of their components. Thus, LEDs have to be checked during the production stage as well as at the end of the process with the PCE-LED 1 light meter. Additionally, within the research and development of LEDs and products with LEDs, a wide optical characterization is always required. Our PCE-LED 1 luz meter allows you to test the LEDs' status quickly and easily.
