Electromagnetic flow meters operate on Faraday's law of electromagnetic induction, which states that a voltage is induced when a conductor moves through a magnetic field

Computer mouse and other pointing devices are used to control the screen-based movement of a cursor or icon on a visual computer. This category includes mice, trackballs, and touch pads

Specialty communication devices use specialized or proprietary interfaces or technologies

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

Electrical and EMC testing services evaluate parts and products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), radio frequency interference (RFI), dielectric properties, conductivity, electrostatic discharge (ESD), insulation resistance, and other electrical characteristics

EMC Testers are devices used to test or monitor parts and products for electromagnetic compatibility (EMC

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

Magnetic sensor chips are semiconductor devices that detect physical quantities using magnetic principles

Magnetic receivers use the electromagnetic principle to receive and analyze signals. The simplest of these devices is the telephone

Machining oil, cutting fluid and coolant filters are industrial filtration products used in metal processing applications to improve performance, product quality, and equipment life (i.e., maintenance schedule, repairs).

Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices

Specialty nondestructive testing (NDT) probes and sensors are specialized or proprietary devices for NDT

Noise figure meters measure the noise contribution of an amplifier relative to a noise-free amplifier at a reference temperature. For most Ku-band amplifiers, values are expressed in decibels (dB).

Industrial keyboards are peripheral hardware devices that include alphanumeric keys, electromechanical buttons, or sensors that users press to interface with a computer.  

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
