Tesla Meter, Tm-400

Product Description

Tesla Meter, Tm-400 

Introduction

TM-400 operates on the principle of Hall Effect in semiconductors. A semiconductor carrying current develops an electromotive force, when placed in a magnetic  field in a direction perpendicular to the direction of both electric current and magnetic  field. The magnitude of this e.m.f. is proportional to the field intensity if the current is kept constant. This e.m.f. is called the Hall Voltage. This small Hall Voltage is amplified through a high stability amplifier, the output of which is processed through a microncontroller and displayed on a graphical LCD display.
