The Model 430 uses the proven UV Absorption principle, producing accurate and stable O3 measurements.
The small footprint and quiet operation make it extremely useful for ambient air and indoor air quality, surveying, and industrial hygiene applications.
Model 430 carries US EPA Federal Equivalent Method EQOA-1015-229 certification.
The Model 430 Compact O3 Analyzer uses the proven UV Absorption principle, to produce accurate and stable O3 measurements. The robust design and low power consumption makes it ideal for portable monitoring applications such as rural and remote monitoring, saturation studies, and atmospheric research.
The small footprint and quiet operation make it extremely useful for indoor air quality, surveying, and industrial hygiene applications. An optional battery pack provides up to 14 hrs of run time on a full charge.
