MK350N Premium handheld spectrometer

MK350N Premium handheld spectrometer Advanced upgrades of operation and speed,
Embedded with spectral technology,
Optimize the LUX measuring range,
Overall, the measuring result becomes more accurate which can be your best reliable helper.
3.5"Color Touchscreen and All New icon Design
Interface is concise, menu is classified clearly and intuitive icon is operational,
Closer to user preferences in experiencing easy and simple style,
It is a Spectrum Analyzer, LED Meter and Flicker Meter for LED manufacture.
Flicker, all lights have it.
Sometimes you can see it, sometimes you can't.
Most of the lighting products with dimming, circuit control systems cause flicker problems.
In any case, flicker can spell trouble of all kinds, with high unpredictable health and safety risks.
●Public security accidents occur frequently.
●It can lead to headache and induced epilepsy attacks.
●Visual fatigue and reduced visual task performance causes the distraction.
●The quality of image shooting quality is hard to maintain,
increasing the post-production cost.
Use the MK350N Premium Spectrometer to fight flicker issues readily.
Add high efficient Flicker measurement Module Complied to the international measuring standards "IES/ASSIST/ENERGY STAR".
Sampling rate is up to 100k Hz which could capture the flicker parameters, light amplitude and light frequency.
It extremely suits for LED professional who are strict at application quality requirements of the light sources.
New Revolution- Evaluating Light-Source Color Rendition We are used to measuring the light quality by traditional parameters such as CRI, GAI, CQS and etc. ,
MK350N Premium embedded the TM 30-15 color rendering index
It is the new method published by IES in 2015.
It not only shows the accurate the light quality, but also enhance the fairness of the measurement.
Providing the lighting evaluation of standard for lighting designers, LED lighting manufacturers and manufacturers objectively.

Build a bridge to 4.0 industry
Save more time.Reduce manufacturing cost,
Efficient USB connectivity up to 16 times,
Efficiency, Speed, Flexibility
MK350N Premium the LED meter for LED Manufacturer.

Free Download Mobile and Pad APP to experience the pleasure of wireless remote control
And MK350N Premium PC Software to analyze the data easily.
Now, uFlicker PC Software free download
It allows you to know the flicker values of different artificial light sources conveniently, Make your flicker quantitative study become more perfectly.
