Overview

Gasboard-3500 is a wall-mounted, explosion-proof (ExdIICT6 Gb) online gas analysis system for fuel gases such as biogas, syngas and natural gas, flexibly measuring CH4, CnHm, CO, CO2, H2, O2, H2S, calorific value and Wobbe index without carrier gas. Automated sampling and drainage enable 24-hour unattended monitoring.

Key Features

  • High-speed response and continuous measurement based on NDIR and other technologies
  • Real time calculation of calorific value and wobbe index
  • No carrier gas needed, replacement to gas chromatography, mass spectrometry
  • Modular sensor design ensures simple maintenance
  • EX-Proof design with CNEX certification (ExdⅡCT6 Gb)
  • Optional air purging module can prolong electrochemical sensor lifetime
  • Thermostatic design for sensors to reduce temperature fluctuation influence
  • All parts contacting with sample gas are made of high corrosion resistant material
  • Auto diagnosis function to check sensor status quickly
  • Capable of measuring multiple sampling channels
