[0026] As Figure 4 , 5As shown, the probe assembly 3 includes a probe rod 31 and a connecting mechanism, which is magnetically attracted to the metal platform 4. The probe rod 31 has a coaxial capacitor structure, which scans from the top to the bottom of the sample cup 2 and then from the bottom to the liquid surface, measures the water content of each layer, and finally calculates the average water content. The connecting mechanism includes a connecting cover 32 and a connecting base 33, which are screwed together. The connecting cover 32 is connected and fixed to the metal platform 4 by the magnetic steel 34 on the top wall of the connecting cover 32.
