Automatic-reading seepage electric simulation experiment instrument

The utility model discloses an automatic-reading seepage electric simulation experiment instrument composed of three components of an SX-1 type signal source (1), a piezoelectric coordinate display (2), and an electric simulation plate (3). An SX-1 type signal source dial is mainly composed of a switch button (4), a digital display (6), a frequency adjustment knob (7), an output adjustment knob (8), and a range adjustment knob (9). The piezoelectric coordinate display (2) part is composed of a digital display (10) and a lug. The lug is connected to a single-chip resistor pressure-sensitive layer (12) of the electric simulation plate (3). The electric simulation plate (3) is mainly composed of a waterproof coordinate paper layer (11), the single-chip resistor pressure-sensitive layer (12), and a support (13). When the instrument provided by the utility model is subjected to a hydropower simulation experiment with unconfined seepage, when an isoelectric point is detected by a probe, the coordinate value of a cu
