In harsh high-pollution environments, precise monitoring of gas concentrations is particularly important. To meet this need, we have specifically introduced a dust-proof and high-temperature resistant gas absorption chamber, which provides a stable and reliable gas sampling solution in high-temperature and severely polluted environments. This gas absorption chamber uses advanced materials and processes, maintaining stable performance within a wide temperature range of -20°C to 200°C. With a high-strength dustproof design, the chamber can effectively resist the invasion of dust and other pollutants, ensuring the long-term stable operation of the equipment.
