The Model 108-L Ozone Monitor is a compact and energy-efficient analyzer designed for accurate ozone measurements from ppb levels up to 20 ppm. Based on UV absorption at 254 nm, it ensures reliable and precise monitoring across a wide dynamic range.

Optimized for integration, this model is specifically engineered to be embedded into existing ozone systems, using the system’s pump for sampling. Its lightweight design and very low power consumption (~2 W) make it ideal for portable, remote, or continuous monitoring applications.

The instrument is EPA approved (FEM), making it suitable for regulatory air quality monitoring and compliance applications.
