Teledyne API products

Teledyne API, a recognized leader in Ozone measurements, is pleased to offer the Model 430 O₃ Monitor. The 430 is a compact instrument that uses the proven UV-absorption principle. The small footprint and robust design make it ideal for a variety of applications where portability and accuracy are both necessary.

The Model 465L UV Photometric Ozone Monitor is an extremely stable analyzer, ideal for critical low-level ppm safety and process applications. Its calibration is NIST traceable and the included pressure and temperature compensation ensure high accuracy under all conditions.

The Model 465M is a microprocessor based medium range ozone monitor for measuring process ozone concentrations in water treatment, food processing, and research applications. The design has been specifically optimized for applications requiring the measurement of ozone at near-ambient pressure such as water treatment contactor off-gas measurement. The Model 465M has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration. The Model 465M is available in a NEMA 4X wall mount enclosure.

The Model 465H is a microprocessor based high concentration ozone monitor for measuring ozone in process gas streams in water treatment, food processing, and research applications.  The 465H has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration.  The Model 465H is available in a NEMA 4X wall mount enclosure.

The Model 452 is a microprocessor based gas sensor for measuring high concentrations of ozone in oxygen or air with accuracy and dependability. The measurement principle is based on the absorption of UV light at 254nm. Readings are available in % by weight, or grams/Normal cubic meter. Temperature and pressure compensation up to 3 Bar Absolute is a standard feature.

The Model 454 is a microprocessor based gas monitor for measuring mid to high concentrations of ozone in oxygen or air. Available in a standard DIN panel mount configuration with a 4-digit LED display, the compact design provides ease of mounting and installation.
