This is a microprocessor-based gas sensor, designed for measuring high concentrations of ozone or oxygen in air with accuracy and dependability. The measurement principle is based on the absorption of UV light at 254nm. Readings are available in percent by weight, or grams/normal cubic meter. It's compact size allows for easy installation in process applications. Two detectors are used in this system, one for the ozone measurement, and the other to compensate for changes in UV lamp intensity. This unique design provides a sensor which will operate for extended periods without calibration or maintenance.
The API-452 also accepts a wide range of flow rates, from 0.5 - 5 LPM, allowing its use for a wide variety of applications.
