Measuring microscopes are used by toolmakers for measuring the properties of tools.  These microscopes are often used for dimensional measurement with lower magnifying powers to allow for brighter, sharper images combined with a wide field of view

Frequency discriminators are RF or microwave devices that are used to detect a signal with a particular frequency

Electric test probes are used to establish a connection between a circuit under test and the measuring instrument

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.

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.

Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield.  Triaxial cables are specialized coaxial cables

Moisture meters are used to measure the moisture content in bulk solids, liquids and gases

Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification

VME switches and VXI switches are used in industrial systems to connect test points, or devices, to instruments for the purpose of testing, measuring or monitoring the system

Digital and video microscopes are instruments that use digital technology to magnify images of objects. They include built-in cameras and a series of high-powered lenses that provide superior image quality and resolution.

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

CRT monitors use cathode ray tube technology to display output from a computer.

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.

Certification services include companies that test, inspect, register and/or certify products, components, equipment, instruments, processes, management systems or facilities. This area also includes organizations that evaluate, audit, assist, train and/or register companies on facility or system wide assessments such as ISO registration, process quality audits, health and safety assessment, and management systems evaluation.    

Optical and light microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects.
