atago pal coffee digital pocket coffee refractometer

Description

atago pal coffee pocket refractometer in perfect condition with the case. reads the tds total dissolved solids (strength) of a sample of filtered coffee and displays it as a percentage, readable to the hundredth of a percent. for example 1.51%, where 1.51% of the liquid sample would be dissolved coffee solids, and the rest is water. this is handy because knowing how strong your coffee sample is tells you if you are getting more (or less) extraction than a previous brew. this helps you test new brew techniques or equipment to see just how they are affecting your extraction level. unlike the VST refractometer, this atago gives you your sample temperature (to a tenth of a degree celcius). this is handy if you wish to enclose your sample in a sample jar (to avoid evaporation of the water portion of the sample) and allow it to reach ambient temperature before taking a reading - a technique with highest reading accuracy with any model of refractometer.
