Electric Furnace Exhaust Gas Oxygen Analyzer
The electric furnace exhaust gas oxygen analyzer adopts imported high-performance electrochemical gas sensors and microprocessor technology. It features functions such as digital display, upper and lower limit alarms, standard signal output, and relay contact alarm output. It is suitable for continuous monitoring of oxygen concentration in gases such as air, nitrogen, hydrogen, and argon.
Main Features:
- The instrument uses a new type of oxygen detector.
- Equipped with a large-screen LCD display and a full Chinese operation menu.
- Real-time clock display.
- Can be connected to a printer to realize timed automatic printing.
- Has a timed automatic storage function, allowing for viewing stored data at any time.
- Features a paperless recorder function, automatically recording the curve of oxygen concentration changes over time.
- Equipped with an RS232 communication port, which can be connected to a computer to realize real-time data transmission, data storage, curve trend graphs, report printing, and other functions.
- Allows setting of upper and lower limit alarm points and has alarm contact output.
- Can be calibrated online with standard gas.
- Optional output current of 0-10mA or 4-20mA.
