🔗 LINKS + MENTIONS: 

The Bionutrient Institute is a project of the Bionutrient Food Association.

The Bionutrient Meter is a handheld spectrometer that works through the principle of spectroscopy. The Bionutrient Meter has lights (LEDs - light emitting diodes) that emit light at very specific wavelengths, which then bounce off objects like carrots, or carrot pulp, or spinach, or soil. Some of it is absorbed by the object and turned into other forms of energy, like heat. A light sensor in the device reads how much light bounces back for each wavelength very quickly and multiple times throughout a given measurement.
