EM-3D electromotive force measuring device use: Replace the traditional instruments such as UJ25 with the power supply, photoelectric galvanometer, and variable resistance box with digital electronic potentiometer. The electromotive force of the primary battery was measured by the elimination method. Features: 1. Adopting integrated circuit design, cancellation balance method, built-in high-precision reference voltage integrated circuit, and output comparison voltage for internal calibration (designed external standard input, standard instrument to correct instrument measurement accuracy). 2. Seven digit display. 3. New long life, micro touch, 360° rotary switch. 4. Low power consumption, low drift, high precision, the latest generation of products. Technical indicators: 1. Measurement range: 0 ~ ± 1.999999V, can be extended to ± 5V 2.Accuracy: 0.005% FS 3. Resolution: 0.001mV 4. Internal benchmark: around 1.25V 5. Specifications: 360 × 235 × 120mm
