Overview

The Gasboard-9021 tri-gas system measures CO, CO2 and CH4 in heat treatment furnace atmospheres in real time with temperature-controlled NDIR sensors. It supports furnace diagnosis, carbon potential calculation and cross-checking of oxygen probes, meets CQI-9 audit requirements and offers an optional TCD module for H2.

Key Features

  • Stable NDIR Tri-Gas Detection: Temperature-controlled NDIR sensors for simultaneous measurement of CO, CO2, and CH4 with minimized drift during long-term operation.
  • CQI-9 Compliance: Meets automotive supply chain audit requirements for process and quality stability.
  • Easy Operation & Maintenance: Integrated gas sampling and conditioning system with modular design for simplified installation and maintenance.
  • Optional H2 Measurement: Optional TCD detector with advanced interference correction technology for accurate H2 measurement without cross-interference from CO, CO2, or CH4.
