Ozone-Gas-Analyzer

Ambient Ozone Analyzer by ultraviolet spectrophotometry principles, combined with the most advanced microprocessor technology, provides accurate and reliable low-content ppb-ppm-level 03 detection, application suitable for atmospheric monitoring requirements.

UV absorption Ambient ozone Analyzer based on Beer-Lambert law for monitoring low concentration of ozone concentrations in ambient air.

A 254nm UV light through the sample cell is absorbed by the ozone in the sample cell, absorption value is proportional to the concentration of ozone. Through the solenoid valve cycle alternating samples through measuring the sample gas and contains no ozone. Finally, we get a real stable measurement of ozone concentration.

Full control over all the functions of this instrument at the same time, can also provide important operating parameters of online instruction. During the measurement, real-time automatic compensation of the temperature and pressure changes.
