The ETB-228 Measurement of Inductance by Hay’s Bridge trainer is a precision educational kit designed to demonstrate the accurate measurement of inductance using the Hay’s Bridge method, a variant of the AC bridge technique. This trainer is ideal for electrical and electronics engineering students, enabling hands-on learning of inductance calculation in high-Q coils, typically used in communication circuits and filters.
The unit features a complete bridge circuit with onboard components, a built-in regulated power supply, clearly labeled test points, and high-accuracy components for stable and repeatable results. The ETB-228 is widely used in instrumentation and measurement labs to teach impedance measurement, AC bridge balancing, and practical application of AC theory in inductive components.
