APMA-370
Ambient Carbon Monoxide Analyzer
The HORIBA APMA-370 is a high-performance ambient carbon monoxide analyzer engineered for continuous, real-time monitoring of CO levels in the atmosphere. Leveraging cross-flow non-dispersive infrared (NDIR) absorption technology, it delivers precise, stable measurements with minimal maintenance—ideal for environmental agencies, industrial facilities, and research institutions.
Why Choose APMA-370
- Global Compliance with CE, TÜV QAL1 (EN 14626), (EU), FCC, U.S. EPA, Japan, China, Korea,
MCERTS (UK), GOST (Russia)Cross‑flow NDIR detector for stable CO measurement - Reference gas purifier oxidizes CO to CO₂ to eliminate interferences
- Internal dry‑method sampling device for high sensitivity
- Mirror‑free optics prevent contamination
- Robust design for continuous ambient operation
