PPB Level Trace O3 Gas Analyzer
Product Features
1.Equipped with a touch color screen that displays rich operational data (e.g., real-time O3 concentration, calibration records, fault alerts) and supports shortcut menu queries for intuitive, user-friendly on-site operation;
2.Adopts a double light pool design that optimizes gas flow paths, improves gas displacement efficiency, and reduces residual gas interference—directly enhancing measurement accuracy and response speed;
3.Supports real-time chart display of instrument span calibration data, allowing users to visually track calibration trends and ensure the reliability of detection results;
4.Integrates automatic pressure & temperature compensation function, which adjusts measurement data in real time according to changes in ambient pressure and temperature, avoiding environmental factors affecting detection precision;
5.Operates stably with high precision and excellent repeatability, requiring minimal professional training for daily use—suitable for both long-term unattended monitoring and temporary on-site testing;
6.Automatically stores calibration data and alarm information (e.g., over-limit alerts), making it easy to track equipment operation status and conduct post-event data review and analysis;
7.Supports one-click query of historical data and personalized display of operation data curves, helping users visualize O3 concentration changes over time and identify pollution patterns;
8.Enables remote software system upgrade, allowing for function updates and bug fixes without on-site visits—saving time and reducing maintenance costs for global users;
9.Features startup self-test and running self-diagnosis functions, which quickly identify faults (e.g., light source abnormalities, flow instability) to help users locate and resolve issues efficiently.
