Decade boxes are versatile electronic devices that allow users to simulate different electrical values for testing and calibration purposes. They typically have multiple switches that allow users to select different resistance, capacitance, and inductance values, and are commonly used in electronics labs, manufacturing facilities, and repair shops. Decade boxes are useful for testing and calibrating a wide range of electronic equipment, including multimeters, oscilloscopes, and signal generators. They can also be used to troubleshoot circuits and diagnose faults. With their compact size and easy-to-use interface, decade boxes are a must-have tool for anyone working in the electronics industry.

Top 8 Decade Boxes
GME RD-300 Resistance Decade Box
The GME RD-300 is a high-accuracy capacitor resistance decade box. This box is designed, engineered and supported in the USA, unlike most other decade boxes on the market. It has a 7-decade wide resistance range from 1Ω to 11,111,110Ω with 1% high accuracy and 1-watt rated resistor design. It is easy to use and versatile, with 28 slide switches that are organized in a clean 4 x 7 grid for easy use. The GME RD-300 is portable and rugged, housed in protective impact-resistant rubber holster with a tilt-stand.
Decade Resistance Box - Ranges Over Four Decades
This standard four decade resistance box used to calculate resistance is ideal for most student experiments. With a range of 0 - 11,110 Ohms in increments of 1 Ohm and ±1% tolerance, it has a maximum power output of 2W, and a lowest amperage of 20mA and highest amperage of 700mA. It is easy to use with resistances selected by the turn of a dial. However, at least 2 banana plug cords, alligator clips, a power supply, and at least 1 multi-meter are required for use but are not included. It is important to set the resistance high enough to maintain a safe power output.
Guanruixin Digital Resistance Decade Box
Enjoy a precise and error-free experience with the Guanruixin Digital Resistance Decade Box. Its fully digital display eliminates calculation errors, while its ultra-wide range values can meet all your needs. Plus, it's small and light, taking up minimal desktop space.
REED R5406 Capacitance Decade Box
The REED R5406 Capacitance Decade Box features three binding posts to permit isolated substitutions and slide switches that allow users to easily add or subtract for desired value. With five decades of capacitance ranging from 100 pF to 11111 Degree F, this box is excellent for circuit development. Its compact size of 5-51/64" length by 4-19/32" width by 2" depth makes it easy to store and transport.
IET Labs RS-200W Wide Range Resistance Substituter
Resistance Decade Box with Dual Display Mode
This Resistance Decade Box is made in the USA and features high accuracy (.0005% between 1KΩ to 1MΩ) and high resolution (0.01Ω). It has simple USB computer control, making it excellent for automatic test equipment (ATE). Additionally, it has programmable quick keys for fast output of desired values and allows users to download user-defined tables to emulate any resistive sensor, including thermistors, strain gauges, and pressure sensors.
GME CD-300 Decade Box
GME Capacitance Box is a portable and rugged decade box designed and engineered in the USA. It has a wide capacitance range from 100pF to 11.111μF in 100pF steps with 5% high accuracy that is ideal for prototyping, educational, and professional calibration of test equipment. The box is easy to use with 20 slide switches organized in a clean 4 x 5 grid, and each switch displays a visible white dot when in the ON position. It also has two binding posts that allow for easy versatile connection with banana plugs, bare wires, spade lugs, or alligator clips. The box is housed in a protective impact-resistant rubber holster with a tilt-stand.
TENMA 72-7270 Resistance Decade Box
The TENMA 72-7270 Resistance Decade Box is a kit of 1 slide-adjustable resistance decade box that measures from 1ohm to 11111110ohm with 7 decades and 300 power rating. It offers an accuracy of 1% and a resolution of 1ohm. The compact size with external dimensions of 33 x 147 x 117 mm and weight of 320 grams makes it portable and easy to use.
Frequently Asked Questions (FAQs)
1. What is a decade box used for?
Decade boxes are ideal for troubleshooting circuits and verifying the accuracy of test equipment, both in the field and in the lab. Decade boxes are test instruments which use a series of resistors, capacitors, or inductors to simulate very specific electrical values.
2. What is a decade inductance box?
These Decade Inductance Boxes allow quick and easy setting of a wide range of Inductance. Selection of Decade switches has been done with best contacts and less residual inductance. Decade Inductance Box is designed to calibrate Inductance Meters and Inductance ranges of LCR meters.
3. What is a capacitance decade box?
The Capacitance Decade Box Model BC05 is built into a metal bench top box. It is used for testing and calibration of test equipment. The main function of the Model BC05 is to create a capacitance with a specific value by using a combination of the rotary decade switches. The Model BC05 has five decade ranges.
