UPRtek Spectrometer MK-350D

UPRtek LED Spectrometer MK-350D

Precise Light metrology in just 3 seconds

The UPRtek MK-350D 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.
The MK350D works connects wireless via Bluetooth with smartphones based on Android or IOS systems


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, 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 MK350D 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. At sizes of 33 x 33 x 90 mm mm and weighing approximately 75 grams incl. batteries this precision spectrometer fits in any briefcase or laptop bag. The MK-350D 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.

It comes with a stand alone 128 x 64 px OLED screen showing data such as CCT, CRI, LUX, FC, R9, Flicker etc, all in series by pressing a button.
All data are shown on your smart phone display via Bluetooth 3.4 / 4.0 wireless connection.

Operation time about 3 hours with fully charged rechargeable battery.

Data can also be saved on SSD card, data tables are compatible with Microsoft Excel
