Wilfa Precision WSP-2: Thermostability And Speed Of Brewing Test

I test the 2nd generation of Wilfa Svart Precision Coffee Maker to find out if it is really so good in terms of thermostability. I use this thermocouple: TM-902C https://ali.ski/B7SvK

In other words, I want to check if it is satisfy the Golden Cup Standard by Specialty Coffee Association (SCA): how fast Wilfa WSFB-100S can achieve the needed temperature 200°F ± 5° (93.0°C ± 3°) and how stable the temperature is.

Spoiler: yes. It takes about 15 seconds to get the temperature above 90°C (274 K). Then, till the end of brewing, Wilfa Precision stays around 92.5°C. My thermocouple isn't laboratory calibrated, of course. However, simple tests with zero and 100°C shows, that Tm-902c has accuracy better than 1%.
