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 chromatographs separate organic chemical mixtures according to physical properties

Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed.

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

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space.

Flow transmitters provide electrical outputs that are proportional to flow inputs.

Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column.
