The measuring range can be customized according to customer needs, and the gas pool heating function is optional.

NDIR (Non-Dispersive Infrared) gas sensor is a type of gas sensor that uses infrared light to measure the concentration of specific gases in a gas sample. It is based on the principle of infrared absorption spectroscopy.

Here are the key features and components of an NDIR gas sensor:

1. Infrared Light Source: The sensor includes an infrared light source that emits light at specific wavelengths in the infrared range. The wavelengths are chosen to correspond to the absorption bands of the target gas molecules.
2. Gas Chamber: The gas chamber or sample cell is a space where the gas sample interacts with the infrared light. It is designed to optimize the path length and interaction between the gas molecules and the infrared light.
3. Optical Components: The sensor incorporates optical components such as mirrors, lenses, and filters to direct and focus the infrared light onto the gas sample and then onto the detector. These components are designed to maximize the sensitivity and accuracy of the measurements.
4. Detector: A detector is used to measure the intensity of the infrared light before and after it passes through the gas sample. The absorption of infrared light by the target gas molecules leads to a reduction in the transmitted light intensity. The detector detects this reduction and converts it into an electrical signal.
5. Signal Processing and Data Analysis: The electrical signal from the detector is processed and analyzed by the sensor’s electronics. The sensor may include calibration algorithms and temperature compensation to ensure accurate and reliable gas concentration measurements.
6. Data Output: The sensor provides an output signal that represents the gas concentration. This output can be in the form of an analog voltage, digital signal, or communication protocol

NDIR gas sensors are commonly used for the detection and measurement of gases such as carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and various hydrocarbons. They find applications in industrial safety, indoor air quality monitoring, combustion analysis , and environmental monitoring. NDIR sensors offer high sensitivity, stability, and selectivity, making them suitable for a wide range of gas detection and monitoring applications.
