Product Introduction
The AG5-1～7 Digital DC Galvanometer is a precision current measuring instrument with multiple ranges, designed for laboratory, industrial testing and educational applications. This product series features advanced digital processing technology to deliver stable and reliable measurement performance, suitable for detecting weak DC currents and bridge balance indication. It offers wide measuring range (0.1-300μA) and broad frequency response (10Hz-10kHz), meeting various precision measurement requirements.39
Key Features
Equipped with 3½-digit LED display for clear readability, the galvanometer adopts left-zero-pointer design to show absolute current values. The internal circuit incorporates low-noise, low-drift operational amplifiers paired with high-precision sampling resistors to ensure measurement accuracy. Range switching covers all specifications from AG5-1 to AG5-7, allowing users to select appropriate sensitivity levels (division value ranges from 2×10-9 to 1.2×10-5A/div). Reasonable input impedance design minimizes impact on measured circuits.210
Applications
This series is particularly suitable for null detection in various DC bridges and potentiometers, and can also function as standalone microcurrent measuring instruments. In education, it s widely used in physics and electrical engineering experiments to demonstrate bridge principles and weak signal detection. Industrial applications include photocurrent measurement and bioelectric signal detection. Its two-dimensional scalar display supports self-assembled AC bridge experiments. User-friendly operation with zero-adjustment and range selection functions adapts to diverse measurement environments.11621
