Description
The student meter double-range volts centre zero is an economical centre-zero galvanometer-style voltmeter for physics and electrical experiments. It provides two DC voltage ranges, 50–0–50 and 500–0–500, allowing students to observe needle deflection to either side of zero for positive and negative voltages in practical circuit work.
The centre-zero layout supports classroom demonstrations in circuit analysis, polarity checks, and Ohm’s law style voltage measurements where direction of deflection is part of the learning. The meter includes a large viewing window for easy group visibility, stated as 90 × 70 cm, and the overall instrument dimensions are stated as 100 × 90 × 95 cm (L × W × H).
