Magnetic field instruments include meters, gauges, recorders and other instrumentation for the measurement of magnetic fields and/or magnetic flux

Magnetic field sensors measure magnetic field strength, direction, and/or magnetic flux. They are used for scientific measurement, navigation, and industrial applications

EMF meters detect and monitor harmful electric, magnetic or electromagnetic fields surrounding personal or work areas

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments

Magnetic speed sensors rely on a magnet as the sensing element or sensed target to capture rotational or linear speed. They are typically used as gear tooth speed sensors or incorporated into stroboscopes or tachometers

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.

Magnetic shielding includes products and raw materials for shielding instruments and equipment from magnetic fields. 

RF field intensity meters measure the strength of an electromagnetic field. These instruments or receivers are used to detect buried or hidden piping, equipment or ferromagnetic ores

Eddy current instruments are nondestructive testing (NDT) devices that induce detectable eddy currents in conductive materials. They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys

Geophysical instruments are used for geological study, including rock and soil mechanics, core analysis and surveys of the earth

Microscopes are instruments that produce magnified images of small objects

Navigational instruments and avionics include GPS devices, compasses, chronometers, radar units and other instruments for orientation, relative position and absolute position (longitude / latitude

Specialized electromagnetic sensors and instruments are proprietary electrical and electromagnetic sensors and instruments not explicitly listed elsewhere

Levels are mechanical or electronic tools that measure the inclination of a surface relative to the earth's surface.

Non-destructive testing (NDT) material testers are devices, machines and equipment that are used to determine residual stress, alloy type, hardness, microstructure, elasticity, heat treatment and other material conditions without permanently altering or destroying the material being examined.
