Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements

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

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

Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.

Environmental testing and analytical services provide testing of environmental samples such as soil, water, air, and industrial wastes or byproducts.

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only

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

Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close

Gas chromatographs separate organic chemical mixtures according to physical properties

Gas generators provide an onsite supply of gas, vapor or humidity (water vapor) eliminating the need for delivery in gas cylinders

Gas filtration elements are designed to remove particulates from a gaseous process stream. They are used in natural gas processing systems and gas extraction applications

Gas compressors and systems are used to circulate gas through a process, enhance conditions for chemical reactions, provide inert gas for safety or control systems, recover and recompress process gas, and maintain correct pressure levels by either adding and removing gas or vapors from a process system

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

Gas purifiers, dryers and filters are used to purify gases in a process stream. They are used to reduce or eliminate point-of-use impurities in gases such as helium, hydrogen, methane, nitrogen, and carbon dioxide

Gas, liquid and solids samplers are used to take samples of media from process streams, reactors or storage vessels
