AR650 Series – Multi-Component Analyser
Home / AR650 Series – Multi-Component Analyser
The OPSIS AR650 is an infrared (IR) gas analyser used in continuous emission monitoring systems (CEMS) and process control to measure compounds like CO, HCl, HF, CH₄, and H₂O via FTIR-DOAS technology.
System Overview & Technology
-Core Measurement: Uses infrared absorption/FTIR-DOAS technology across stacks or ducts.
-Gases Monitored: Carbon monoxide (CO), hydrogen chloride (HCl), hydrogen fluoride (HF), methane (CH₄), water vapor (H₂O), and carbon dioxide (CO₂).
-Config Components: Links an emitter/receiver assembly across a flue gas stack via fibre optic cables to the central AR650 analyser unit.
Official Certifications
TÜV / QAL1 Approval: Tested and certified according to EN 15267 standards (e.g., TÜV Test Report for AR650/NHF).
MCERTS & Regional Compliance: Certified for industrial plant emission requirements globally and verified via schemes like CSIR-NPL for local regulatory standards.
Measuring Parameters
