Accurate and Portable Ozone Monitor
Teledyne API developed an accurate, portable, and easy to deploy ozone instrument: the Model 430 Compact Ozone Monitor. The Model 430 uses the traditional UV-absorption principle to produce accurate
and stable measurements of ozone in ambient air.

• DC power capability
• Dimensions H x W x D = 4.2" x 7.1" x 10.2"

Applications

• Ambient Air Monitoring
• Water Treatment
• Food & Beverage

UV Absorption Technology:

Measuring ozone by UV absorption provides the highest accuracy and reliability in ozone monitoring. Unlike electrochemical or metal-oxide sensors, UV absorption directly measures ozone using its natural absorption of ultraviolet light at 254 nm. This method is absolute, meaning it does not drift, degrade, or require frequent recalibration. As a result, UV analyzers deliver long-term stability and precise readings even in demanding industrial or water-treatment environments.

Sensor-based ozone monitors depend on chemical reactions inside the sensor element. These sensors gradually degrade, drift over time, and are affected by humidity, temperature, and the presence of interfering gases. They require periodic recalibration and sensor replacement - adding cost and reducing measurement certainty.  The UV Absorption technology eliminates most all cross-sensitivities from interfering gases in the air.

UV Absorption Technology provides:

• Highest accuracy and repeatability
• No drift and minimal calibration requirements
• Excellent long-term stability
• Minimal, or zero cross-sensitivity from competing gasses in the environment
• Minimal influence from humidity and temperature changes
• Direct, real-time measurement of true ozone concentration
