Aeroqual AQM60 User Guide
1.1. Control Module
The control module is the interface between the RS485 sensor bus and data communication links. It contains
a display, a SD data card which logs data, a RS232 serial connector for external communication, a bus
connector for internal communication with the sensor modules and a cable connector for the Sensirion
Humidity and Temperature sensor (if fitted).
The AQM60 is supplied with a RS232 to USB adapter fitted between the Control Module and an external
USB socket fitted at the side of the enclosure. This enables the user to perform a wide range of functions
over the USB connection, without needing to open the enclosure door, such as data logging and various
system checks using the supplied Aeroqual AQM60 PC software
Note: The driver for the RS232 to USB adapter is in the software CD which comes with the
instrument.
1.2. Gas Treatment Module
The Gas Treatment Module controls the gas sampling. Inlet air is filtered through a 5 μm membrane filter and
enters the Gas Treatment Module via either the sample or zero air ports. The air is then distributed via a
PTFE manifold to the gas modules. A solenoid controls the air path which can be switched from the directly
sampled ambient air to air which has passed through internal scrubbers (zero air) in order to check the
baseline readings of the gas sensors.
