Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display

Projectors receive data from a computer or video source and project this data onto a screen via internal light sources, power sources and converters

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).

Frequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals

Multi-input display processors combine multiple signals from real-time video and computer inputs on a single high-resolution projector of monitor

Audio visual service providers design, integrate, and install multimedia equipment for corporate, production, and broadcasting applications.

Oscilloscopes translate an electronic signal into a pattern or waveform on a screen. As it is traced across the screen, the waveform creates a signature of the signal's characteristics.

Video camera lenses attach to video cameras for use in machine vision, quality monitoring, security, and remote monitoring for industrial and commercial operations. This search form does not cover consumer video camera lenses. 

Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.

Audio switch matrices are electronic switching instruments for interfacing audio signals in scanning, recording and analysis systems.

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.

Engineering consulting firms provide engineering services and expertise to companies in need of a specialized skill-set.  Professionals in this category work with clients to define solutions to problems or to help determine and recommend the best course of action for a given initiative.

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.
