Description

Introduction:
The NDUV gas bench Gasboard-2300 series of sensors uses non-dispersive ultraviolet absorption (NDUV) technology and a highly stable pulsed LED UV source. In pulse mode, the UV beam passes through the measurement chamber and is absorbed & attenuated. The measured gas concentration can be calculated according to Lambert-Beer law. Different from the UV differential method, our NDUV gas bench can accurately measure the gas concentration of SO2, NO, NO2, H2S, O3, with high measurement accuracy and strong anti-interference.

Features:
• High stability pulsed LED ultraviolet light source
• Dual channel design for high precision
• Suitable for ultra-low range monitoring
• Direct measurement of NO2 without NOx converter
• In-built constant temperature heating device
• Automatic temperature and pressure correction
• Modular design for easy integration & maintenance

Specification:
Measurement: SO2, NO, NO2,H2S
Range:
SO2,NO:0~100~2000ppm
NO2,H2S:0~500~5000ppm
