At Creativeit Group we have a wide variety of measuring devices for laboratories, technicians, and electronics students.
We have this instrument, the PRECISE CAPACITOR DECADE 478
With four decades with 10x ranges: 100pF, 1nF, 10nF, 100nF.
A “capacitor decade” generally refers to a set of capacitors that can be combined in various ways to achieve different capacitance values in decades. In electronics, capacitance values usually follow a logarithmic scale, and each decade represents a tenfold increase or decrease in capacitance.
For example, a capacitor decade box is a device used in laboratories and electronic testing to provide a range of capacitance values by combining capacitors in series or in parallel. Each dial or switch on the box normally represents a decade, allowing the user to select capacitance values in powers of 10 (1x, 10x, 100x, etc.).
These capacitor decade boxes are useful for tuning circuits, testing equipment, and conducting experiments where variable capacitance is required. They provide a convenient way to change capacitance values without having to swap individual capacitors manually.
