Overview

Gasboard-9031EX is an explosion-proof (Ex d IIC T4 Gb) online syngas monitoring system measuring CO, CO2, CH4, H2, O2, C2H2, C2H4, CnHm and calorific value. A heated stainless probe with auto-purge, two-stage filtration and cooling, and PLC automation enable 24/7 unattended monitoring in furnaces, metallurgy, CDQ and chemical plants.

Key Features

  • Multi-Gas Measurement: Simultaneously detects CO, CO₂, CH₄, H₂, O₂, C₂H₂, C₂H₄, CnHm and calculates heat value.
  • Robust Sampling Probe: Stainless steel, heated dry-extraction design with auto-purge function,ensures reliable operation in dusty environments.
  • Dual-Stage Filtration & Cooling: Removes moisture and particles to ensure stable long-term performance of the analyzer.
  • PLC-Controlled Operation: Fully automated sampling, backflushing, and drainage, enableing 24/7 unattended monitoring.
  • High Safety Standards for Hazardous Areas: Certified with Ex d IIC T4 Gb explosion-proof rating, making it safe for use in flammable and potentially explosive environments.
