HORIBA’s AP-380 Clears UK’s MCERTS Test for Continuous Air Monitoring

Air-quality monitoring is becoming less about occasional measurements and more about proving emissions data continuously. HORIBA’s AP-380 Series has now cleared an important regulatory hurdle in the UK, securing MCERTS certification for ambient air monitoring.

MCERTS is the UK Environment Agency’s framework for ensuring environmental monitoring equipment meets defined performance standards. Its ambient-air standards cover continuous monitoring systems and are used to assess whether instruments are suitable for regulatory-quality measurements.

The AP-380 is designed for continuous trace-gas measurement, covering gases including CO, SO₂, O₃, NO, NO₂, NOₓ, methane, NMHC and THC. It can measure concentrations from the ppb to ppm range, making the platform relevant to both ambient monitoring and industrial applications.
