▎Product Introduction ：
The RD330 Online Oxygen Analyzer employs a high-precision electrochemical sensor to detect oxygen concentrations in various environments. It transmits data and triggers alarms via (4–20) mA analog signals, RS-485 communication signals, or switch alarm signals, while displaying real-time measurements. Its explosion-proof design ensures reliable operation even in harsh conditions.This product is suitable for online monitoring of constant or trace oxygen levels across industries including industrial hydrogen production, natural gas blending with hydrogen, iron and steel metallurgy, petroleum and chemical processing, medical pharmaceuticals, and semiconductor manufacturing.
▎Key Features ：
1.Wide-range measurement: Capable of detecting both trace and constant oxygen leaks.
2.Temperature and pressure compensation: Built-in temperature compensation sensor and atmospheric pressure compensation for high measurement accuracy.
3.Local display function: Features an LCD screen for convenient on-site operation and monitoring.
4.User-friendly operation and maintenance: Intuitive interface and rational instrument design for easy daily maintenance.
