Q: In this task, you need to Translate Czech text to English.
Vynález se týká konstrukce kontaktní konduktometrické  sondy s nastavitelnou hodnotou  konstanty sondy. Sonda je určena především pro  měření elektrické vodivosti kapaliny. Sondu tvoří  elektricky nevodivý nosník elektrod a vlastní  elektrody, z nichž alespoň jedna je v nosníku  elektrod uložena na závit a její činná délka je  pomoci tohoto závitu měnitelná. Změnou činné  délky elektrody lze nastavit požadovanou konstantu  sondy.
