A ultra-compact, portable electronic scale that utilizes miniature strain gauge technology to provide highly precise, on-the-go digital mass readings. Perfect for field-testing, field biology, weighing micro-reagents, and quick jewelry or component checks, this pocket-sized instrument is also widely known as a portable milligram scale, mini digital balance, or jewelry pocket scale.
An electromagnetic moving-coil instrument that operates on the principle of magnetic torque, where the current pulse is integrated over time due to high coil inertia to measure total electric charge. Ideal for physics laboratory experiments involving the measurement of transient currents, mutual inductance, and capacitor discharge, this sensitive device is also commonly known as a charge-measuring galvanometer or ballistic mirror galvanometer.
