Wall Mount Air Quality Monitor SQ30
Wall Mount or Desktop Air Quality Monitor SQ30
Santacary SQ30 is a high precise instrument mainly used to continuously monitor the carbon dioxide (CO2) concentration, particulate matter PM2.5, PM10, the temperature and the relative humidity in ambient air.
High level CO2 in ambient air may cause fatigue, loss of concentration, and illnesses such as Sick Building Syndrome. Fine particles PM2.5 refers to fine particulate matter in ambient air aerodynamic equivalent diameter less than or equal to 2.5 micron particles. It was suspended for a long time in the air. The higher the fine particulate concentration and the carbon dioxide concentration in the air, the worse the air quality is. Studies suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. The Wall Mount Air Quality Monitor SQ30 converts the concentration of CO2, PM2.5 in the air into visual data, and evaluates the air quality comprehensively.
SQ30 can be widely used in the houses, office, school, meeting room, restaurants, hospitals, mining facilities, metal refineries, commercial and public buildings, agriculture greenhouse, and other places where confined spaces for personal health and personal comfort is important. Santacary SQ30 is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

THEORY OF OPERATION
1. CO2 Measurement: SQ30 uses Dual Beam Non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air. Automatic Background Calibration (ABC) is disabled.
2. PM2.5 and PM10 Measurement: SQ30 uses a laser scattering theory to obtain the number of particles in the equivalent particle size and volume units of different size through the algorithms based on MIE theory.
