UJ33D/2 Digital Display Potentiometer Product Introduction
The UJ33D/2 digital display potentiometer is a high-precision electrical instrument developed with digital measurement technology, specifically designed for laboratory research, industrial field testing, and educational applications. By integrating advanced signal processing modules and intelligent computing units, this device enables rapid measurement of DC voltage, electromotive force, and other parameters, providing reliable measurement solutions for temperature sensing, material analysis, and circuit debugging scenarios.
Equipped with a high-resolution LCD screen, the device supports 4-digit effective value display for intuitive measurement readouts. The measurement range covers 0-2V with a minimum resolution of 0.01mV, ensuring accurate detection of weak signals. The built-in auto-zero function effectively eliminates environmental interference, while the temperature compensation algorithm maintains ±0.05% measurement accuracy within 10℃-40℃ operating conditions. The dual power supply system supports both AC/DC operation, complemented by rechargeable lithium battery packs to accommodate both stationary laboratory use and mobile field measurements.
The user interface features an ergonomic layout with a function selection knob and confirmation buttons, allowing complete operation processes including range switching and mode selection through single-knob control. The aluminum alloy casing combined with internal shock absorption structure enhances impact resistance. Standardized interfaces enable data interconnection with computers and recorders for experimental data storage and analysis.
In practical applications, this instrument is widely used in thermocouple calibration, sensor verification, battery performance testing, and finds extensive utilization in chemical, metallurgical, and electronics manufacturing industries. The educational version incorporates an operational guidance system with step-by-step prompts to facilitate understanding of measurement principles and standardized procedures.
