SOX NOX AMBIENT ANALYSER

Continuous Ambient Air Quality Monitoring System

The APSA-370 Ambient SO₂ Monitor and the APNA-370 Ambient NOx Monitor are advanced continuous monitoring instruments designed for measuring atmospheric sulfur dioxide (SO₂), nitrogen oxides (NO, NO₂, NOx), and related pollutants with high accuracy.

Both analyzers use proprietary internal dry-method sampling technology, enabling continuous real-time analysis of gases in their natural state with minimal maintenance requirements. The dry-method system ensures long-term stability, high sensitivity, and reliable data unaffected by external moisture or interfering components.

These systems are ideal for use in ambient air monitoring networks, pollution control applications, and compliance reporting.
