Oxygen analyzer 700 LX

processindustrialconcentration

Overview
ENVEA 700 LX is a modular analyzer platform for continuous measurement of oxygen and infrared‑detectable gases. The system combines NDIR multi‑gas capability with paramagnetic or fuel‑cell oxygen measurement to provide stable, percent‑scale O2 readouts and multi‑component analysis for process and emissions monitoring.

Details
The 700 LX supports mixed configurations: up to three infrared (NDIR) channels or two NDIR channels plus one oxygen channel (paramagnetic or fuel‑cell). Measured oxygen concentration is displayed as a percentage on the LCD. Automatic calibration and auto‑range selection are available. The analyzer features temperature and pressure compensation, fast response, and a robust Linux‑based operating system for reliable continuous operation. Remote control and monitoring are possible via RS‑232, TCP/IP or digital inputs.

Features and benefits

• O₂ measurement ranges from 0–1% (paramagnetic only) up to 0–100% full scale (four definable ranges)
• NDIR multi‑gas measurement combined with paramagnetic or fuel‑cell O₂ measurement
• Automatic calibration and automatic range selection
• Fast response times (T90 ≈ 5 s paramagnetic, 16 s fuel‑cell)
• Temperature and pressure compensation for stable readings
• Robust Linux operating system for continuous operation
• Remote operation and control via RS‑232, TCP/IP or digital inputs
• Comprehensive diagnostics and status reporting
• Standard outputs: voltage, current, RS‑232 AK, TCP/IP, MODBUS or AK protocols

Typical applications

• Combustion efficiency monitoring
• Process gas analysis
• Fuel cell testing and analysis
• Turbine and generator feedback/control
• Personnel safety monitoring
• Vehicle emissions testing
