In order to meet the needs of foreign markets and provide cost-effective instruments, based on UV Differential Optical Absorption Spectroscopy (DOAS) technology, Hanran's technical team adopts a modular design to launch a high-precision UV gas analyzer, which can quickly and reliably measure the concentration of various gases in flue gas. It adopts a 7" high-definition true color digital screen, with beautiful appearance and friendly operation interface. After the sample test, it was highly recognized by foreign customers, indicating that it will continue to cooperate in batches in the near future.
