Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

RF generators and high frequency power supplies provide the power required for plasma generation, induction heating, and radar or communications applications

Welding machines and joining machines include all manner of devices used for welding, brazing and soldering.

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems.

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.

Plastic welders consist of torches, ultrasonic welding equipment, heat guns, hot rod welders, RF or dielectric welders, and hot plate welders used to join thermoplastic materials

Wafer and thin film instrumentation includes quartz crystal microbalance (QCM) monitors, ellipsometers, RHEED systems, imaging stations, CD-SEMs, ion mills, and C-V systems specifically designed for wafer metrology or in-situ monitoring of thin film parameters during thin film or semiconductors wafer processing.

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.

Bias tees allow the insertion of DC voltages into a signal path without disrupting the existing signal in that path.

Industrial ceramic materials are non-metallic, inorganic compounds that include oxides, carbides, or nitrides. They have high melting points, low wear resistance, and a wide range of electrical properties.

Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics.

Oxide ceramics include alumina, zirconia, silica, aluminum silicate, magnesia and other metal oxide based materials.

Biological microscopes are used to study organisms and their vital processes.
