With the rapid development of industrial automation and intelligent manufacturing, gas monitoring has become a crucial element in ensuring production safety, enhancing process quality, and optimizing energy management. Carbon dioxide (CO₂), a common gas in industrial processes, is widely used in sectors such as food processing, chemical manufacturing, welding, refrigeration, fermentation, and HVAC. However, an abnormal rise in CO₂ concentration can not only disrupt production processes but also pose risks to the health and safety of personnel. Consequently, selecting a CO₂ sensor that offers stable performance and precise measurement is a key consideration for industrial equipment manufacturers and system integrators.

    TX721-A2 infrared CO₂ gas sensor utilizes advanced Non-Dispersive Infrared (NDIR) detection technology. Specifically designed for industrial-grade CO₂ monitoring, it features high precision, a long service life, and strong anti-interference capabilities, making it suitable for a wide range of industrial environments and capable of providing continuous, reliable gas detection support for equipment.
