Precision DC Potentiometers Models 2722 and 2723 are high-quality DC potentiometers. Utmost care has been taken in the selection of materials, components, and circuit design to insure high accuracy and stability. These potentiometers are recommended for use in test rooms and laboratories as secondary standard instruments or in work shops and inspection departments of factories for fine checking. Model 2722 measures voltages from 10 mV to 1.6V at an accuracy of 0.01% in five or six digits. Model 2723 is especially designed for low-voltage measurement from O.1� V to 111 mV at an accuracy of 0.01% in five or six digits.
