The AQT530 measurement data is available over RS-485 by means of Modbus (ASCII and RTU modes), or alternatively in ASCII CSV format.

The measurement data can be monitored also through CLI.

The following tables present the measurements, their units, and resolution.

Set of available gases depends on gas cell setup.

Particle measurement results are included when an LPC device is installed and enabled.
