⭕ General Radio 1621 Precision Capacitance Measurement System.

When used with an oscillator and a detector equivalent to the 1316, 1238 and 1616 Capacitance Bridge will perform as follows: A wide range of capacitances can be measured, extending from the resolution limit of 0.1aF to a maximum of 10uF with internal standards, and further with external standards. For 3-terminal unknown capacitors, a pair of coaxial terminals is provided; for 2-terminal coaxial, a single precision connector facilitates exacting control of fringing effects. Equipment is less than 2 years old. Delivery/Pickup. In good condition, works fine.
