  A thermocouple converts temperature information into a weak electrical signal (a resistance‑based signal) and uses a temperature controller to measure temperature; it offers small measurement errors and high accuracy. The probe you mentioned, on the other hand, senses temperature by exploiting the physical properties of the medium inside the probe and drives an analog pointer‑type thermometer via thermal conduction; it has lower sensitivity and larger measurement errors, but places fewer demands on the application environment.
