MK350S Premium is a full-featured Handheld Spectrometer used by lighting professionals with wide ranging projects and lighting challenges.
The MK350N Premium is our popular mid-range spectrometer, made for professionals who want top spectrometer performance without the need for specialized niche features (e.g. Manufacturing , PAR meter, Lighting Design).
The MK350D Compact spectrometer is for users who just need a simple product with basic measurements essentials. And yet, the measurement needs to be precise and up to the scrutiny of global standards.
The PG200N is a Spectral PAR meter used to measure the quantity and quality of light for a new generation of indoor farmers who use artificial lighting as a substitute or complement to sunlight.
The CV600 spectral color meter is for cinema and stage lighting professionals, providing tools to help assess/adjust color fidelity, improve color rendering, purchase better lights, recall lighting setup from previous performances and make better overall choices about lighting with the numbers.

What is a "Spectral" PAR Meter
Valentine’s Day is approaching, and you're an anxious indoor rose farmer trying to encourage your buds to bloom in time.
The good news is that researchers have begun to understand the triggering mechanisms for seed germination, flowering, and fruiting, involving grow-light strategies
Now indoor farmers are using this information with “Spectral” PAR meters, measuring grow lights for a light metric PSS (Phytochrome Photostationary State) to trigger photomorphogenesis (i.e., plant transformations caused by light).
