How does an NDIR CO2 Sensor Work?

NDIR CO2 Sensor NDIR is an industry term for “nondispersive infrared”, and is the most common type of sensor used to measure carbon dioxide, or CO2. The CO2 sensor works by directing light waves from an infrared lamp through a tube filled with air samples. This air moves toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation also produced by the lamp is very close to the 4.26-micron absorption band of CO2. Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or “fingerprint” to identify the CO2 molecule. As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the ... Continue reading →

Introduction EC or Electrical Conductivity of water is its ability to conduct an electric current. We have a special water EC detector to detect the EC content. Salts or other chemicals that dissolve in water can break down into positively and negatively charged ions. These free ions in the water conduct electricity, so the water electrical conductivity depends on the concentration of ions. Salinity and total dissolved solids (TDS) are used to calculate the EC of water, which helps to indicate the water’s purity. The purer the water the lower the conductivity. To give a real-life example, distilled water is almost an insulator, but saltwater is a very efficient electrical conductor. Major positively charged ions that affect the conductivity of water are sodium, calcium, potassium and magnesium. Major negatively charged ions are chloride, sulfate, carbonate and bicarbonate. Nitrates and phosphates are minor contributors to conductivity, but they are very important ... Continue reading →

1. What is carbon monoxide? What does CO do to the body? Carbon monoxide gas is colorless, odorless, and difficult to be discovered. But people are very dangerous if they are in carbon monoxide, and even threaten their lives. At room temperature, carbon monoxide can mix with air to form an explosive mixture. It can cause combustion and explosion in the case of open flames and high temperatures. It is a flammable and explosive gas.When the body inhales excessive carbon monoxide, hemoglobin will lose its ability to carry oxygen and cause suffocation, and even death in severe cases.We can use CO sensor for online monitoring. 2.

How Does NDIR Gas Sensor Work?

Technology: A NDIR gas sensor working principle is based on the property of certain molecules to absorb light at specific wavelengths (or “color”) that are characteristic of their molecular structure. The absorption characteristics are defined as molecular vibrational energies associated with stretching, bending or rotations and depends upon the molecular structure of the gas. For IR energy to be absorbed, that is for vibrational energy to be transferred to the molecules, the frequency must match the frequency of the mode of vibration. Thus, specific molecules absorb IR radiation at precise frequencies and each gas has a unique and well defined light absorption curve in the infrared spectrum. When IR radiation passes through a volume containing a specific gas, only those frequencies matching the vibration mode are absorbed, while the rest of the light is transmitted without interference. For this reason, the presence of a particular gas gives rise to ... Continue reading →
