Hoogprecisie-instrumenten voor luchtkwaliteitsmonitoring, deeltjesmeting en milieuanalyse – gebouwd voor betrouwbaarheid, nauwkeurigheid en naleving van de regelgeving.
The HORIBA APNA-380 is a high-performance ambient NOx monitor designed for continuous, high-precision measurement of Nitrogen Oxides in the atmosphere. Utilizing the advanced Cross-Flow Modulation Chemiluminescence method, the APNA-380 delivers the sensitivity and stability required for the most demanding air quality monitoring networks.
As a part of the 300-series ambient monitors, the APNA-380 is engineered for long-term reliability, minimal maintenance, and compliance with international environmental standards.
The APNA-380 provides simultaneous and continuous monitoring of:
NO (Nitrogen Monoxide)
NO2 (Nitrogen Dioxide)
NOx (Total Nitrogen Oxides)
The APNA-380 uses the Cross-Flow Modulation Chemiluminescence (CLA) method.
Superior Stability: By alternating the flow between sample gas and reference gas, the system eliminates zero-point drift and the need for frequent optical adjustments.
Innovative Ozone Generation: The unit features a highly durable, non-depleting ozone generator and a proprietary de-ozonizer that converts O3 back into O2, enhancing both safety and instrument lifespan.
Low Detection Limits: Capable of measuring at the ppb (parts per billion) level, making it ideal for background ambient monitoring.
The APNA-380 is recognized worldwide for its accuracy and reliability, holding major certifications including:
TÜV (Germany): Certified for use in official air quality monitoring networks (EN 14211).
US EPA: Designated as a Federal Reference Method (FRM) or Equivalent Method.
MCERTS (UK): Performance-tested for environmental monitoring.
CE Marking: Fully compliant with European safety and emission standards.
The APNA-380 is the industry standard for various environmental and industrial monitoring scenarios:
Ambient Air Quality Monitoring (AAQM): Integration into national and regional monitoring stations.
Roadside & Tunnel Monitoring: Real-time analysis of vehicle-related emissions.
Industrial Perimeter Monitoring: Tracking emissions around refineries, power plants, and chemical sites.
Research & Development: High-accuracy data collection for atmospheric chemistry studies.
Intuitive Operation: Large color LCD touch screen with trend graphs and status indicators.
Easy Maintenance: Front-access design allows for quick filter changes and service without removing the unit from the rack.
Smart Data Management: Internal data logging with storage for up to one year of 1-minute values.
Remote Connectivity: Ethernet and RS-232 interfaces for seamless integration into telemetry systems.
Reduced Gas Consumption: Optimized design reduces the amount of sample gas and consumables required.
