The VST LAB Coffee III Refractometer is a tool that has been used for measuring coffee & espresso Total Dissolved Solids (TDS) to understand the efficiency and quality of brewing through extraction.
VST Labs have advanced the Refractometer with the latest fourth-generation that provides laboratory precision that comfortably fits into the palm of your hand. The Lab III Refractometer has an expected accuracy of +/- 0.02% and worst case precision of +/- 0.1%.
Designed for the rapid and accurate calculation of coffee concentration within a sample, an automatic temperature compensation has been programmed to automatically correct for temperature within the range of 15-40cº.
Advanced Sapphire Optics backed by a 1024 Element Detector Array boost precision and improve accuracy to +/- 0.03% in the Filter coffee sample range and +/- 0.05% in espresso sample range. The super fast reading will automatically average multiple measurements and than display the resulting TDS as a decimal reading, easily converted to a percentage out of 100%.
Using the built-in Auto ranging TDS Scale you can explore and understand the nuances of flavour vs strength vs extraction and begin to catalogue effective ways to make better tasting coffee.
An ambient light shield and evaporative cover protect the stainless steel sample well and optics. Intended for use in commercial settings, the VST Lab Refractometer adopts a durable rugged rubber armour jacket to sustain the tough cafe and kitchen environment.
With the added option of VST CoffeeTools Software, (Window or MacOS) you'll gain access to further tools to be used alongside the VST LAB Coffee III Refractometer to calculate the extraction yield and other variables.
