Null Detector
Product Code : JA-SI-8083
The Null Detector (SKU JA-SI-8083) shows the balance point of an AC bridge on a meter instead of by ear. It is built around a solid-state amplifier whose output stage drives a meter, so it can take the place of the head phone that older bridge set-ups rely on. The circuit sits in a metal cabinet finished in Duco paint, with an aluminium front panel.
