Teledyne API 430 Compact Ozone Monitor

The Teledyne API Model 430 is a compact ozone analyzer that uses UV absorption for accurate O₃ measurements. It offers a user-selectable concentration range from 0–100 ppb to 0–20,000 ppb with a precision of <0.5 ppb or 0.5% above 100 ppb. It includes an SD card data storage, low power consumption (9W), and a 10,000-hour pump life. The analyzer is certified as a US EPA Federal Equivalent Method.
