The Extech 380400 and 380405 decade boxes feature durable construction cases that may be grounded separately and 3 binding posts which permit isolated substitutions. Both models are designed for reliable performance in educational and industrial settings.

The Extech 380400 resistance decade box offers 1% resistance substitution from 1 to 11,111,110 Ω with seven decade ranges. Values can be set in 1Ω increments, making it suitable for a wide range of resistance simulation needs.

The Extech 380405 capacitance decade box offers 5% capacitance substitution from 100pF to 11.111µF with five decade ranges. It features 50pF internal zero capacitance and provides accurate capacitance values for circuit development and testing.
