Dissolved CO₂ instruments are analytical devices that measure the amount of carbon dioxide (CO₂) dissolved in a liquid sample such as water.

Total organic carbon (TOC) analyzers measure the amount of total organic carbon present in a liquid sample.

Carbon dioxide (CO₂) lasers use the energy-state transitions between vibrational and rotational states of CO₂ molecules to emit at long IR, about 10 µm, wavelengths.

Gas sensors interact with a gas to initiate the measurement of its concentration.

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

Laser cutting machines, laser welding machines and laser marking systems use high-powered lasers to cut, trim, perforate, weld, or join a variety of materials in plate or sheet form.

Industrial gases are pure elements, molecular compounds or mixtures that are gaseous or vaporous at room temperature and pressure.
