Gas transmitters consist of an enclosure, sensor, and electronics that convert a signal from a gas sensor into an analog output signal (typically 4-20 mA

Gas and air instruments detect, monitor or analyze gases present in an environment

Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage

Residual gas analyzers (Rags) identify the gases present in vacuum environments

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

Gas tube arresters (GTA) or gas discharge tubes (GDT) provide protection against voltage and current surges in electronic and electrical equipment

Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute
