Galvanometer, Premium

This galvanometer, specifically designed for use by students, is sturdy but sensitive instrument for the measurement of small currents. The instrument has centre-zero scale and three current ranges and is electronically protected against overload, tolerating overloads of up to up to A for at least 10 seconds. • DC ranges: ± 5 mA; ± 500 μA; ±50 μA • Centre-zero scale • Precision: ± 5 % of full scale • Internal resistance: ± 5 mA: ca. Ω; ± 500 µA: ca. 90 Ω; ± 50 µA: ca. 900 Ω • Electronically protected against overload • Dimensions: 158 x 108 x 56 mm • Scale length: 72 mm
