Application
Application of 7530 AZ CO2 Analyzer Controller:
The 7530 AZ CO2 Controller has the big LCD, which could show the CO2 concentration value with chart, so the 7530 AZ could be used for the CO2 monitor for the indoor air quality and green house CO2 measurement. It could be also operated and met with all work space, office, hospital, school, station, residential, commercial building or home usage.

The 7530 AZ CO2 meter also can control the related instruments easily by two models, including the plant and human models, which could be override the controlling in low or high CO2 concentration.

An external CO2 sensing probe of 7530 AZ CO2 Controller is included to help user measure CO2 level in a closed space, the cable is 4.5 meter long to extend your measure spot 4.5 meter away from display.

The 7530 AZ CO2 controller could control the other connected devices, such as CO2 generator or ventilation fan. It could be used for the horticulture, greenhouse, hydroponics, organic indoor gardening, mushroom farm and lightening industry.

The 7530 AZ CO2 Controller was being designed and manufactured by AZ Instrument, a well experienced manufacturer of CO2 Controller.

FAQ

【FAQ of AZ 77294 CO2 7530 AZ CO2 Controller NDIR Monitor with Relay Control】


Q1: Which plug types are available for the 7530 CO2 Controller?
A: To ensure global compatibility, the 7530 AZ is available in four regional plug and socket versions: USA, EU Schuko, EU France, and UK version. This allows users to connect local CO2 equipment without additional adapters.

Q2: How does the "Day/Night" mode save on CO2 costs?
A: The built-in photo-cell sensor detects light levels. In Plant Mode, it automatically stops CO2 release during the night when plants do not perform photosynthesis, preventing gas waste and optimizing growth cycles.

Q3: What devices can I connect to the 7530 relay output?
A: The integrated relay socket supports devices up to 5A/250VAC or 10A/120VAC, making it compatible with most CO2 generators, regulators, solenoid valves, and ventilation fans for automated climate control.
