UPRtek LED Flicker-Spectrometer MF-250N

Precise Light metrology in just 3 Seconds

The UPRtek MF-250N is a portable spectrometer for measurement of various optical values ​​of the visible light for human eyes, in particular matched to the light from LED / OLED light sources as well as conventional light sources, such as Fluorescent tubes, energy saving lamps, incandescent lamps, sodium-vapor lamps, high-pressure lamps.

This low-cost, yet high-quality spectrometer is characterized by ease of use, precision measurement, high repeatability as well as the increasingly important measurement of light flickering.

Flicker measurement:
Flicker or fibrillation is the permanent periodic variation of light brightness, mostly caused by AC-powered light sources or pulsed controlled (dimmed) LEDs. This fibrillation often causes headaches, premature fatigue, malaise and in the photographic and film technique substantial impairment of shots. As a lighting designer, lighting designer, set designer, photographer, cameraman, workplace representative and not least as a developer and manufacturer of lighting it is important to have particularly flicker-free light.The MF250N has been optimized for the measurement of light flickering, but provides additional lighting basic data like light spectrum, color temperature, color rendering index, brightness, and much more.The integrated light sensor detects the entire light spectrum from 360 nm to 780 nm. The UV and IR waveband is not recorded. The measured values ​​of color rendering and flicker measurement have an accuracy of +/- 5% - unprecedented for a portable instrument in this price range accuracies comparable to much more expensive laboratory instruments. The menu language on the LCD color display is English.

The measurement is performed with a single keystroke to the "Capture" button on the right side. The data is displayed in the 5 sub-menus for Basic, range, Flicker, FFT and Lightwave. However, storing the data as the larger devices MK350N, MK350N + and MK350S is not möglich. At sizes of 180 x 65 x 30 mm and weighing approximately 270 grams incl. batteries this precision spectrometer fits in any briefcase or laptop bag. The MF-250N is an indispensable instrument for those who need to make light measurements in the field, especially in advising on the changeover to the energy-saving LED lighting technology.
