Extech Decade Boxes

A Decade Box houses several precision resistors (ohms), capacitors (F), or coils (H) organized in decades of ten (ex. 10, 100, 1000, etc.). Decade boxes are used to check and calibrate test equipment.

Considerations when purchasing a Decade Box
  • Know the minimum accuracy required
  • Know the range
  • Know the power or current to be used for measurement
  • Is it for simulating a PT100 RTD temperature probe?
  • Know the application or instrument being calibrated
