UPRTek LED-Spectrometer MK-350N-Premium

Follow-up of the classical MK350N+ - same style but additioonal measures.

The MK350N-Premium allows to select from 40 measures, 4 individually displayed in the basic Screen.

New measures are e.g.
Delta UV: - to measure UV-% in light
Flicker: - to measure flicker%, flicker frequency, flicker index of light sources
CQS: - Color Quality Scale
TLCI: - Television Lighting Consistency Index
TM30-15: (Rf, Rg, Color Vector Graphic)
SVM: Stroboscopic Effect Visibility Measure
SPD: Spectral Power Distribution mW/m²
SP-Ratio: scotopic / photopic ratio
CIE-1921: X, Y, Z
CRI Ra: R1~R15

Easy to use, handheld LED spectrometer to measure all visual light from 380 nm to 780 mm at any time.
This ultra precise spectrometer comes with a CMOS Linear Image Sensor, 3,5" color touch screen, USB 2.0 port, SD-card slot.
It is supplied with pouch, comes with rechargeable battery, power driver - all in a robust aluminium case to carry with you when you're on the road.
Asmetec supplies the MK350N-Premium fully inspected and with charged battery - simply switch on and start your work.

Unlike any other spectrometer the MK-350N-Premium offers you the complete range of MUST HAVE light data such as:
Illuminance in Lux, spectral irradance, CIE coordinates 1931 and 1976, peak wave length, correlated color temperature (CCT) in Kelvin, color rendering index Ra (rendering average, but also R1~R15), Flicker-Measure, TM30-15 Mode, Frequency mode and many more.

All data can be saved to SD-card (not included) or to your computer as MS-Excel compatible file or as BMP-file.
The fully charged battery operates the system for about 5 hours continiously measure (can be one time / continuos measure)
It includes an automatic dark calibration when switched on. Auto off function (time adjustable), menu language english, chinese, japanese. German and french language.
The MK-350-N-Premium comes in a robust aliuminium case, including pouch, rechargeable battery, charger, manual, 4GB SD-Card,

Display languages are English, Trad. Chinese, Japanese, Spanish, German, French, Italian, Russian.

It can work for up to 5 hours with fully charged battery (2500 mAh, 3.7 V Li-Ion-rechargeable battery is included).
Data output by SD-Card, SDHC up to 32 GB, Mini USB-Port, WiFi SD-Card compatible with IOS and Anroid

How to use? Easy as can be:
1. Make sure the sensor cap is on sensor
2. press power button and accept automatic dark calibration
3. take off sensor cap and hold the sensor to the light source in dedicated distance
4. press measure button until beep
5. read measure in different ways via difference screens
6. (if needed) save data to SD-card or to your computer
