Product Overview
The UJ27C DC Potentiometer is a portable high-precision instrument designed for measuring DC potential in laboratories, industrial sites, and educational settings. This self-contained unit features built-in transistor amplifier galvanometer, standard cell, and DC regulated power supply, eliminating the need for external accessories. With a measurement range of 0-2.110V and resolution down to 5μV, it achieves ±0.1% basic accuracy. The compact chassis (280×225×160mm) weighing 4kg ensures excellent portability for field applications. 2912
Key Features
This potentiometer incorporates intelligent galvanometer system with startup self-check function and fault prompts. The user-friendly interface supports Chinese display with real-time monitoring display. Multiple analysis modes are available including single/dual wavelength methods, endpoint method, kinetic method, etc. Unique features include sample pre-dilution function, automatic retest capability, and power failure protection that resumes previous operation. The environmentally friendly power system combines dedicated cleaning solution with warm distilled water rinse for measurement stability. 11326
Applications
Ideal for university physics/chemistry labs, it can directly measure 1.5V dry cells or 2V batteries. Industrial applications include calibration of millivolt meters and electronic potentiometers. When paired with standard resistors, it expands functionality for DC resistance and current measurement. The wide operating temperature range (5℃~35℃) and corrosion-resistant design ensure reliable performance in workshops and field environments. Multi-level password protection provides operational security. 202228
Maintenance
Store in environments below 80% humidity without corrosive gases. Annual calibration is recommended, with batteries removed during prolonged storage. New batteries require 20-30 minutes discharge for current stabilization. Replace 6F22 9V laminated battery if galvanometer sensitivity declines. Regular rotation of switches minimizes contact oxidation. Comprehensive after-sales guidance enables users to perform routine maintenance easily. 102728
