Application
Application of 7755 AZ CO2 Meter:
The 7755 AZ portable CO2 detector could measure the indoor air quality index, including the CO2 concentration, CO2 level, CO2 level, air temperature, dew point, wet bulb temperature and humidity. The Carbon Dioxide value can be output to PC for on-line analysis. The CO2 sensor can be calibrated easily in the fresh air, and the RH sensor could be calibrated with AZ 33%/75% salt bottle.
The 7755 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 7755 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 7755 AZ CO2 & Temperature & Relative Humidity Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.

【FAQ of AZ 7755 CO2 monitor】
Q1: Why is NDIR technology preferred for the AZ 7755 CO2 monitor?
A: NDIR (Non-Dispersive Infrared) technology is a "true" CO2 measurement method. It is highly specific to CO2 molecules, meaning it won't give false readings in the presence of perfumes, alcohol, or other cleaning chemicals, unlike cheap semiconductor-based IC sensors.
Q2: Does the AZ 7755 measure more than just CO2 levels?
A: Yes, it is a 3-in-1 environmental monitor. It simultaneously measures CO2 concentration, air temperature, and relative humidity, providing a more comprehensive overview of indoor air quality and thermal comfort for HVAC diagnostics.
Q3: Can this device calculate long-term exposure levels?
A: Yes, the device automatically calculates and displays TWA (8-hour Time Weighted Average) and STEL (15-minute Short-Term Exposure Limit) to help assess workplace safety.
