## Long description

AZ Instruments AZ 7530 is a CO2 monitor and controller engineered to measure and regulate indoor carbon dioxide concentrations. The device combines an accurate CO2 sensor with control output to maintain a configurable setpoint, enabling automated ventilation management and real-time monitoring of air quality in occupied spaces. Its design supports integration with ventilation systems and alarm or control equipment for continuous environmental control.
Advantages
The AZ 7530 provides continuous CO2 measurement with control capability, reducing the need for manual adjustments of HVAC systems. It supports reliable regulation of CO2 setpoints through control outputs, helping maintain target concentrations for comfort and safety. The unit offers straightforward installation and system integration, with clear readout and alarm/control interfacing suitable for technical and non-technical users.
Suitable for
Classrooms and educational facilities where CO2 control supports concentration and ventilation management
Offices and meeting rooms requiring automated ventilation based on occupancy
Greenhouses and controlled-environment agriculture where CO2 levels affect plant growth
Laboratories and research spaces that need regulated indoor air composition
Ventilation systems and building management installations for demand-controlled ventilation
Key specifications
Function: Continuous CO2 monitoring with control output for maintaining setpoint concentrations
Measurement: Carbon dioxide concentration measurement suitable for indoor environments
Output: Control/alarm output(s) for direct integration with ventilation or alarm systems
Installation: Wall- or panel-mountable form factor for fixed indoor placement
User interface: Clear display and controls to view CO2 values and adjust setpoint(s)
How to use
Install the AZ 7530 at breathing level in the monitored space, away from direct drafts, windows, doors, and local CO2 sources to ensure representative sampling. Connect the control output to the ventilation or alarm equipment according to the system wiring guidelines. Power the unit and configure the desired CO2 setpoint and alarm thresholds using the device interface. Verify operation by observing the display and confirming that control outputs activate when measured concentrations cross configured thresholds.
Usage recommendations
Place the device in a central location of the occupied area at approximately seated or standing breathing height (typically 1–1.5 m above the floor). Periodically check calibration and sensor performance as recommended by facility policies or the manufacturer to maintain measurement accuracy. When integrating with HVAC controls, use the controller outputs to implement demand-controlled ventilation strategies to balance air quality and energy use.
