Application
Application of 7752 AZ CO2 Meter:
The 7752 AZ portable CO2 detectorcould measure the indoor air quality index, including the CO2 concentration, CO2 level and air temperature. The Carbon Dioxide value can be output to PC for on-line analysis.
The 7752 AZ CO2 device could be used as the CO2 checker for the air quality index in all workspace, office, hospital, school, station or home. It can be calibrated easily in the fresh air and its back light function could let user operate in the dark area. The 7752 AZ is your best choice as the indoor air quality (IAQ) testers.
Poor indoor air quaintly is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex: sick building syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as office, classroom, factory, hospital, work space, residential, commercial building and hotels. It is also suggested in regulations of industrial hygiene in some countries.
The 7752 AZ CO2 & Temperature Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.

【FAQ of 7752 AZ Portable Indoor Air Quality Temperature CO2 Meter】
Q1: What are the advantages of the NDIR sensor in the AZ 7752?
A: The Non-Dispersive Infrared (NDIR) sensor provides superior long-term stability and high specificity to CO2. Unlike low-cost IC sensors, it is not cross-sensitive to humidity or other volatile organic compounds (VOCs), ensuring professional-grade accuracy in diverse indoor environments.
Q2: Can the AZ 7752 be used for workplace safety compliance?
A: Yes. The device tracks TWA (8-hour Time Weighted Average) and STEL (15-minute Short-Term Exposure Limit) values. These metrics are essential for occupational health standards to ensure ventilation systems effectively maintain CO2 levels below safety thresholds.
Q3: How do I calibrate the AZ 7752 to maintain its accuracy?
A: The AZ 7752 features a user-friendly manual calibration function. By placing the device in fresh outdoor air (approximately 400ppm CO2) for several minutes, the NDIR sensor can be recalibrated without the need for specialized calibration gases.
