A Digital Gaussmeter is an electronic instrument used to measure the strength and direction of magnetic fields with high precision. It operates based on the Hall Effect principle, where a Hall probe senses the magnetic flux density and converts it into an electrical signal that is displayed digitally in units of Gauss or Tesla. The device typically features a high-resolution digital display, providing accurate and stable readings of both AC and DC magnetic fields. It is widely used in industries, research laboratories, and quality control departments for testing permanent magnets, electromagnets, relays, motors, and magnetic sensors. Most modern digital Gaussmeters come with selectable ranges, auto zero adjustment, polarity indication, data hold, and calibration options for enhanced usability. Compact, lightweight, and easy to operate, a digital Gaussmeter is an essential tool for professionals dealing with magnetic measurements and material testing applications.

If the fault is electrical the EMC-28N will immediately detects it, without dismantling the equipment. The instrument has three separate operating modes to measure different types of faults like fully insulation, open circuits / loose connections, short circuits, Ground faults and rotor defects. Motor insulation is tested

with a high voltage at 500VDC supplied by the instrument.

NOISE: (Electronic stethoscope) Listening to machine sounds in order to determine the probable source of abnormal noise is one of the most widely used methods in maintenance departments across all branches of industry. Our electronic stethoscope is a practical and easy-to-use listening device that helps pinpoint the source of mechanical noise in a broad range of applications. Bearing condition, gear and pump noise, and electric relay operation are just a few of the many sounds which can be identified, amplified, and assessed.
