Technical Advantages

Standardized and modular design for simple and reliable composition.
Based on UV differential absorption spectroscopy (DOAS) technology, the innovative multi-parameter joint estimation and interference cancellation algorithm realizes extremely low zero drift and span drift over a wide temperature range.
Adopts PLC control with high automation level. The liquid crystal screen displays the system flow path and collects detailed status information of the system, which can be used as the most favorable resource for data validity verification.
