Non-Dispersive Ultraviolet (NDUV) gas technology measures gas concentrations by detecting how much UV light is absorbed by a sample gas as it flows through a cell. It uses a UV light source, a filter, and a detector to achieve high sensitivity and fast, stable, and accurate readings, especially for ozone (

, and

cap S cap O sub 2

Measurement Principle: NDUV operates based on the principle that specific gases absorb ultraviolet light at characteristic wavelengths in direct proportion to their concentration.
Target Gases: Common applications include ozone,

Key Advantages:
- High Sensitivity & Stability: Ideal for low detection limits.
- Selectivity: Provides interference-free measurements with high selectivity, even in the presence of water vapor or hydrocarbons.
- No Consumables: Offers low maintenance compared to electrochemical sensors.
- Fast Response: Provides near real-time measurement results.
Technological Components: Modern sensors utilize reliable, long-life UV-LED emitters [] combined with drift-compensating reference detectors [] for enhanced accuracy.
Application Areas: Widely used for environmental monitoring [], CEM (Continuous Emission Monitoring), biogas measurements [], and process gas analysis [].
Combined Techniques: Often combined with NDIR for multi-gas analysis, enabling the detection of up to six different gases, according to Wi.Tec-Sensorik [].
