When measuring the sample, the exact number of solids dissolved in the prepared coffee (TDS) is obtained. After entering the result into the VST application, a comparison of the sample with the ideal extraction rate is obtained. Thanks to this, we know what parameters we need to work on to achieve the best results.
The VST Coffee Tools application offers the possibility of measuring in the range of 0.0 - 20.0% TDS. Measurement accuracy has been improved in the latest version: filter coffees have been introduced: +/- 0.03%, espresso +/- 0.05% and the possibility of averaging more results and temperature stabilization. In addition, the backlit display makes it easy to read the result, and the sample space is easy to maintain due to the steel surface and flap.
The device is powered by two AAA batteries, which can withstand more than 4,000 measurements with the backlight on.
The device is made in the USA.
