Jul 11, 2017· The MH-Z19 CO 2 sensor manufactured by Winsen Ltd. About the MH-Z19 CO 2 sensor. The MH-Z19 sensor is manufactured by Winsen Lt., China and the measurement method used is based on the non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air. Key features according to the manufacturer are: good sensitivity.
NDIR CO 2 gas sensing have been reported in literature with N 2 [, , ] or synthetic air [, , ] used as a reference and mixing gas. In this work, we test CO 2 gas responses in N 2 and synthetic air respectively to observe NDIR CO 2 gas responses in both gases. The gases pass through their respective mass flow controllers (MFCs) before entering a ...
NDIR sensors are spectroscopic sensors to detect CO 2 in a gaseous environment by its characteristic absorption. The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light.
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.
The Non-Dispersive Infra-Red (NDIR) measurement principle is the industry-standard method of measuring engine exhaust CO & CO₂ concentration. Conventional NDIRs have response times of 1-2 seconds, and are typically used to measure 'bag emissions' where the concentration changes very slowly.

Capnography is a good example for NDIR spectroscopy, where the CO 2 concentration in the exhaled breath of a person is monitored over expired volume or time. By evaluating the five characteristics of a capnogram, , frequency, rhythm, height, baseline and shape, deductions about the health of the patient can be drawn. For this purpose, both ...

Non-Dispersive Infrared (NDIR) techniques for the measurement of various gases rely on the energy absorption characteristics of a particular gas in the infrared region. In a simple NDIR instrument, Infrared energy passes through two identical tubes and falls on a detector. The first tube is the reference cell and is filled with a non-absorbing ...
NDIR analyzers accommodate the analysis of a wide range of gases, including carbon dioxide (CO 2), carbon monoxide (CO), methane (CH 4), and sulfur dioxide (SO 2). Below we outline how NDIR analyzers are used to analyze these gases in different industrial applications. CO 2 Analyzers
