Coffee Refractometer Vst

Thanks to that we know which parameters should we work on in order to obtain the best results.

Coffee refractometer vst. The vst coffee refractometer is temperature corrected. Devices such as a vst lab coffee iii refractometer can be used to find the total dissolved solids tds in a brew. Vst a tech development company owned by coffee obsessive vince fedele developed the first coffee specific refractometer by building upon existing refractometer technology which measures the temperature and the refraction of light in a liquid sample. Advanced optical engine with 1024 element detector array and sapphire optics.

Although refractometers have been around since the late 19th century only recently have they been widely used by coffee professionals. When measuring a sample we obtain a precise number of solids dissolved in the prepared coffee tds. The refractometer will shine light at the sample through this prism. Vst lab coffee espresso iii refractometer features include.

Having entered the result to the vst app we receive a comparison of our sample with the ideal level of extraction. Automatically averages multiple measurements and displays the resulting tds in 2 3 seconds. Vst lab coffee espresso iii refractometer features include. Improved precision 0 01 improved accuracy 0 03 in coffee range 0 05 in espresso range automatically averages multiple measurements and displays the resulting tds in 2 3 seconds advanced optical engine with 1024 element detector array and sapphire optics.

Improved precision 0 01 improved accuracy 0 03 in coffee range 0 05 in espresso range. It s the only refractometer i recommend if you want accurate and consistent results. Each unit is tested for accuracy against a known standard and typically reads to an extrapolated accuracy of 0 05 from 15 30 deg c although the warranted accuracy is 0 1. It already has a presence in some places thanks in large part to vst inc the company responsible for the first ever coffee refractometer they are now on the 4th generation.

This is accurate enough for most applications for coffee in the field. Similarly to a regular refractometer a coffee refractometer can be used to identify extraction amounts and measure caffeine concentration in coffee. Vst lab coffee iii refractometer with coffee espresso scale free soft case updated lab iii version with improved temperature resolution precision accuracy and battery. This is vst s lab coffee refractometer.
