Ozone analyzer - high sensitivity UV measurement: Model 106-L | 2.B Tech

The Model 106-L Ozone Monitor is a high-sensitivity analyzer designed for both ambient air monitoring and industrial ozone applications. Using UV absorption at 254 nm, it provides accurate measurements from low ppb levels up to 20 ppm.

Part of the Model 106 series, this instrument features a robust design with components directly mounted on a printed circuit board, ensuring high reliability, reduced maintenance, and long-term stability. It is available in standard, industrial, or OEM configurations for flexible deployment.

The Model 106-L is EPA designated as a Federal Equivalent Method (FEM), making it suitable for regulatory compliance and environmental monitoring applications.
