Null Detector Digital

Null Detector Digital

The null detector comprises a solid state amplifier having output stage with meter indication. The instrument is supplied in metal cabinet with Duco paint & Bakelite front panel. The said detector has been designed for use with AC bridges (replaceable of headphone). While performing the experiment with four arm bridges, bridge oscillators & headphones are required in almost all the four arm bridges. Sometime good quality headphones are not available & also audibility of each student is different from the another. That's why teachers are switching to null detector in place of headphone.
