Analog Micro Voltmeter

Applications: 'BESTO' Spot Galvanometer finds extensive use as a D.C. null detector in wheat stone bridges and potentiometers. The Micro voltmeter is an effective and robust replacement for a spot galvanometer, with 9 ranges from 100μV to 1V. The input resistance of 1kΩ gives 10MΩ/V on 100μV range, which is considerably better than a spot galvanometer. The instrument has a large moving coil meter, with auto-zero facility.
