Overview

Gasboard-3500 is a wall-mounted online TDLAS analyzer measuring CO, CO2, H2S, H2O, O2 and CH4 from ppm to percent levels without cross-interference or frequent calibration. Ex dIICT6 Gb rated with no moving parts and self-diagnostics, it serves natural gas processing, petrochemicals, refining, power and biomethane upgrading.

Key Features

  • High Precision Detection: Utilizes TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology for high selectivity, sensitivity, and stability.
  • Flexible Measurement Capability: Precise measurement of CO, CO₂, H₂S, O₂, and CH₄ with measurement range from ppm to 100%.
  • Robust Industrial Design: Ex dIICT6 Gb rated, suitable for harsh environments in oil & gas, petrochemical, and power generation industries.
  • Long-Term Reliability: No moving parts, minimal drift, and integrated self-diagnostics ensure long-term reliability.
  • Smart Data Management: Analog and serial outputs for remote monitoring.
