UPRtek MK350N Portable LED Spectrometer

MK350N Spectrometer

The UPRtek MK350N Spectrometer is the first truly compact, lightweight illuminance spectroradiometer which can be used without a computer for evaluation of next- generation lamps such as LED, OLED and EL illumination, as well as, conventional architectural and stage/ studio lighting, even lab research applications.

With its advanced sensor and outstanding design, it can easily measure CCT(Correlative Color Temperature), CRI (Color Rendering Index), illuminance, chromaticity, dominant wavelength, spectral distribution of virtually any light source in the lab or out in the field.

User friendly design, simple menu and 3.5 inch touch screen interface with color graphics make it the ideal tool for multiple applications within the lighting industry.

Reading appears instantly in easy to read full screen color graphics and measurement results stored via an SD card in raw data MS Excel and BMP formats.

The MK350N Spectrometer comes with certificate of calibration to NML/CMS standards, and can be re-calibrated at any time with its internal Dark Calibration feature.

Application

MK350N Spectrometer is a powerful tool for almost all applications of visible lights spectrum analysis in lighting industry, for example:

◆ LED,OLED R&D,QC, Sales, Purchase
◆ Light source Spectrum,CCT,CRI evaluation
◆ Outdoor advertising screen test
◆ Computers and mobiles backlight modules test
◆ Automotive Lighting / Guiding
◆ Street / Tunnel Illumination
◆ Indoor Illumination / Decoration
◆ Museum / Displaycabinet light design
◆ Lab and field scientific research applications

Excellent operation experience

The time spent for fluent processes started from booting to zeroing calibration, to data capturing to diagrams form-up to data storage is just within a few seconds!

◆ On-site measuring, in-time reading!

Just bring your portable MK350 to the site and point it directly to testing light source, then push "integrate button", the spectrum graphic will show up in no time, connecting to PC won't be a need anymore.

◆ Clear-cut data list, your reading is also clear at the first sight!

In Simple mode, you can also read CCT(Correlative Color Temperature)、CRI(Color Rendering Index)、Lux (Illuminance)、λP (Peak Wavellength) ddirectly without the need of mode switching.

◆ 4 modes available to cover all facets

Mode 1：Spectrum Graph Mode
Mode 2：Under Basic Value Mode, to read CCT(Correlative Color Temperature)、CRI(Color Rendering Index)、Lux (Illuminance)、λP (Peak Wavellength)
Mode 3：CIE 1931 Chromaticity Diagram Mode
Mode 4：CIE1976 Chromaticity Diagram Mode
With these 4 modes, you can switch directly from one to any another as you request

◆ Continuous monitor and nothing can vanish from your sight

Except for the single-time capture mode, MK350 is also proud of its continuous capture mode which allows users to adjust the light source's Chromaticity, or to patrol along the light sources to measure the interior lighting. The data (on-screen display) snaps and updates once per second so as to get real and complete pictures in dynamic case.

◆ Complete storage for your access anytime, anywhere!

All captured data are stored in SD card, in both Excel and BMP file formats, the former is for keeping spectrum information, and the other is for the 4 modes' diagrams. Both can be transferred via USB port connection.

◆ Touchpad interface, easy and user-friendly even for newcomers

MK350N combines the latest OS, humanized-design interface, straightward Manu, and all these combines in one 3.5' touchpad, even newcomers can use without any difficulty.
