Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input.

Specialty analog linear devices are specialty or proprietary products and accessories related to analog linear devices

Sound level meters and noise dosimeters are used in sound and noise analysis.

Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.

Annunciators and graphic display panels disclose the layout and annunciate the status and measurement parameters of industrial processes, security and fire alarms of buildings and manufacturing facilities, power distribution networks, and other operations.

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.

Level sensors are used to detect liquid or powder levels, or interfaces between liquids.
