About This Product
A digital panel meter adds a clear numeric readout to a home-built power supply, trainer board or test jig. Engineering and electronics students fit it when building circuits so they can read output voltage or load current directly. Educational Instrument can arrange export supply of the Digital LED Panel Meter to Iceland, Belgium, South Africa, Kenya and Estonia.
