Datasheet
Features
CH14-B precision decade standard capacitance box is a standard capacitance measuring instrument designed for measurement institutes, research institutes, factories and laboratories. The capacitance range is from 100pF to 111.1110μF with a minimum step of 100pF and zero-switch capacitance less than 0.00005pF. The capacitance box has six-digit decade readings.
This capacitance box has both three-terminal and four-terminal output modes and can be connected to the instrument through BNC socket. Three-terminal output is on the right side and four-terminal output is on the left side.
The capacitance box adopts new-structure changeover switch, high-quality capacitor synthetic material, and precision standard capacitor manufactured through special processing. It has stable and reliable capacitance and is easy to use.
