CD-950 TVOC Analyzer
Product Introduction
The CD-950 TVOC Analyzer is a professional total volatile organic compounds (TVOC) measurement instrument designed for accurate analysis of VOC concentration in environmental and industrial applications.
The analyzer adopts catalytic oxidation-NDIR (Non-Dispersive Infrared Absorption) technology, which provides stable relative sensitivity to different VOC components. By converting VOC compounds into carbon dioxide through catalytic oxidation and measuring the CO₂ concentration difference before and after oxidation, the CD-950 accurately calculates the total VOC concentration.
With high measurement accuracy, stable operation, and simple detection principles, the CD-950 TVOC Analyzer is especially suitable for environments where carbon dioxide concentration changes are relatively small, providing reliable VOC composition analysis and air quality assessment.

• Suitable for environmental and industrial VOC monitoring.

Working Principle
The CD-950 TVOC Analyzer operates based on the catalytic oxidation-NDIR (Non-Dispersive Infrared) measurement principle.
First, the analyzer measures the original carbon dioxide concentration in the sample gas. Then, the sample passes through a catalytic oxidation chamber, where VOC components are oxidized and converted into carbon dioxide.
The instrument measures the CO₂ concentration after oxidation. The difference between the original CO₂ concentration and the oxidized CO₂ concentration corresponds to the VOC concentration in the sample.
This method enables stable and accurate measurement of total volatile organic compounds regardless of individual VOC component types.
