HI759 Maple Syrup Digital Grader

Hanna’s Maple Syrup Digital Grader bridges the gap between visual grading kits and professional instrumentation. Temporary maple syrup grading kits provide minimal accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine the percent light transmittance. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The HI759 Maple Syrup Digital Grader uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at an affordable price.
