The APNA-380 is an analyzer for measuring nitrogen oxides in ambient air and other background gases, for air quality control as well as for variety of industrial applications. HORIBA’s state-of-the-art cross-modulation chemiluminescence enables high sensitivity and stable real-time continuous measurement.

*Standard specification is wired LAN connection. For wireless connection, separate device is required.

* In-house comparison with previous model.
