Online Carbon Dioxide Analyzer – Trace, Percent & Purity CO₂ The CO2-525X Carbon Dioxide Analyzer combines a rugged wall-mount enclosure with Southland Sensing’s precision NDIR carbon dioxide sensor technology. The result is a highly reliable, cost-effective analyzer designed for continuous CO₂ measurement in industrial process applications. The CO2-525X is available with full-scale measurement ranges from 0–1,000 ppm through 0–100% CO₂, including high-purity ranges of 50–100%, 70–100%, 80–100% and 90–100%. Multiple sensor and range configurations allow the analyzer to be tailored to trace, percent or purity carbon dioxide applications. The analyzer features a large backlit display with an intuitive user interface for easy setup, calibration and operation. Standard outputs include 4–20 mA analog output, configurable alarm relays and bi-directional MODBUS RS485 ASCII communication, allowing easy integration with a PLC, DCS or other process control system. Integral USB data logging allows measurement data to be recorded directly to a removable USB flash drive. Data is stored in an Excel-compatible .CSV format with selectable logging intervals from 1 to 120 minutes. The CO2-525X utilizes precision non-dispersive infrared (NDIR) sensor technology for excellent accuracy, stability and sensor life. The sensor is self-contained and requires minimal routine maintenance with no electrodes to clean or electrolyte to replace. The compact anodized aluminum enclosure is suitable for indoor or outdoor installation and is available with configurable 1/8", 1/4" or 6 mm compression tube gas connections.
