Infrared Gas Analyzer

Infrared gas analyzer. The 7300 series of non dispersive infrared ndir gas analyzers feature fast response high accuracy sensitivity stability and excellent linearity. Instrument is an important monitoring method for. Since then we have supplied customers with various types of gas analyzers to support environmental preservation and control efforts. The heart of these microprocessor based analyzers is a temperture compensated.

A maximum of 5 gas components can be measured simultaneously and continuously. An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. The concept behind the technology can be understood as testing how much of the light is absorbed by the air. This analyzer is spectroscopically a high resolution analyzer with excellent sensitivity and background rejection.

An infrared gas analyzer made using the principle of absorption of infrared radiation by this gas molecule has the characteristics of high measurement accuracy fast speed and continuous measurement in the industrial departments of iron and steel petrochemicals fertilizers machinery etc. Different molecules in the air absorb different frequencies of light measuring the absorbed frequency clearly gives the relation to. The classical dual beam infrared analyzer can use one or two sources both are available today a measurement or sample cell a sealed reference cell and a gas filled luft detector. Gas selectivity is achieved through the use of optical filters that provide both a means of detecting the gas of interest and compensating for interfering gases and water.

The amount of gas is determined by amount of a particular frequency of light absorbed by the gas when the light is passed through the gas. An infrared gas analyzer is used to measure the quantity of various gas. 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. The range of fuji electric multi gas extractive analysers consists of non dispersive infrared gas analysers.

The cost competitive measurement solutions are due in part to the uniquely designed patented ir detector. Fuji developed the first infrared gas analyzer in japan to use mass flow sensors. The heart of these microprocessor based analyzers is a temperture compensated. Co co 2 nox so 2 ch 4 and n 2 o by ndir technology simple or double beam.

Trace gases found in the earth s atmosphere become excited under specific wavelengths found in the infrared range.
