Gauss meter GS-100D measure for the magnetic induction intensity magnetic fields

Description

Spec：
Used for measuring the magnetic induction intensity of DC magnetic field, AC magnetic field, radiation magnetic field, remanence magnetic field, earth magnetic field, and other magnetic fields.
Features
* Portable, wide range.
* Easy to operate, clear LIQUID crystal display.
* There are measurement/peak retention, mT/Gs unit conversion.
* 200mT/2000mT range conversion, etc.
Principle
The tension sensor is based on Hall's principle.The circuit uses a low drift amplifier and a high stable power supply, controlled by a single chip microcomputer, and displays the measured values on a 41/2LCD.
