7. Specifications
The Aeroqual handheld monitors have been specifically designed to incorporate Aeroqual’s in-depth
knowledge of accurate ambient gas measurement and can be used with a wide range of gas sensor
heads. The sensor heads are interchangeable and therefore multiple heads can be used on the same
base unit. The sensors are calibrated prior to delivery.

*All of the transistor outputs are open collector current sink. The maximum rating of these transistor
outputs is 12VDC at 150mA. Should you connect a relay or any other inductive load to the transistor
outputs, a back EMF suppression diode must be fitted across the load.
