LECO Testing, also known as LECO Combustion Testing, allows the identification of combustion gases in a metal or alloy test subject. This testing method can detect the presence and precisely measure the concentration of several different gases, including oxygen, hydrogen, carbon, nitrogen, and sulfur.

The LECO system requires only a nominal sample weight, and analysis involves oxidizing the sample material using an induction furnace. During the combustion process, carbon is converted to CO2 and measured with an infrared detector.

“LECO” is actually an acronym for “Laboratory Equipment COmpany.” But truth be told, LECO does more than just manufacture lab equipment. That's why each and every person plays an important role within the company. It all starts with an idea…

LECO continues to be a family-owned company in its third generation of leadership and is recognized globally as a leader in the development of high-quality elemental and thermal analysis equipment, mass spectrometers and chromatographs, metallography and optical equipment, and consumables.
