Horiba, Ltd. (堀場製作所, Kabushiki-gaisha Horiba Seisaku-sho) is a Japanese manufacturer of precision instruments for measurement and analysis. They make instruments that measure and analyze automobile exhaust gas (80% share of the world market), [ 4 ] and environmental, medical and scientific applications.
CEMS typically consist of analyzers to measure gas concentrations within the stream, equipment to direct a sample of that gas stream to the analyzers if they are remote, equipment to condition the sample gas by removing water and other components that could interfere with the reading, pneumatic plumbing with valves that can be controlled by a ...
It is the first improved analyzer that is able to detect more than one component of a sample gas at one time. Earlier analyzers were held back by the fact that a particular gas also has lower absorption bands in the infrared. The invention of 1975 has as many detectors as the number of gases to be measured.
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
A classical exhaust gas analyser. An exhaust gas analyser or exhaust carbon monoxide (CO) analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the Lambda coefficient measurement is the most common.
ORSAT analyzer. An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to ...
Masao Horiba (堀場 雅夫, Horiba Masao, December 1, 1924 – July 14, 2015) was a Japanese businessman who was the founder of Horiba Ltd., a manufacturer of advanced analytical and measurement technology. He founded the company as Horiba Radio Laboratory in 1945.
Elemental Analyzer System. The most common form of elemental analysis, CHNS analysis, is accomplished by combustion analysis. Modern elemental analyzers are also capable of simultaneous determination of sulfur along with CHN in the same measurement run. [3] [4] [5] [6]
