KGD-WQ-520 Ultraviolet NOₓ Emission Analyzer
Product Overview
The KGD-WQ-520 Ultraviolet NOₓ Emission Analyzer is used for low-emission detection of vehicle exhaust. This new-generation nitrogen oxide analyzer is independently developed based on ultraviolet absorption spectroscopy gas analysis technology.
Key Features
- Utilizes ultraviolet absorption spectroscopy gas analysis technology to reduce gas cross-interference
- Sampling flow has minimal impact on NO and NO₂ measurement with strong anti-interference capability
- Low detection limit meets requirements for vehicle exhaust low-emission detection
- Internal automatic zero-adjustment air pump for automatic air zero-adjustment
- Self-diagnosis function for online sensor status monitoring
- Communication interface for easy data transmission and integration with other exhaust gas analysis equipment
