Indoor Air Quality Monitor SA80

INTRODUCTION
Congratulations on your purchase of this Santacary SA80 Indoor Air
Quality Monitor. Santacary SA80 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
Indoor Air Quality Monitor SA80 converts the concentration of CO2,
PM2.5 in the air into visual data, and evaluates the air quality
comprehensively.
SA80 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
SA80 is shipped fully tested and calibrated and, with proper use, will
provide years of reliable service.
Please read this manual carefully before use. This user manual will provide
you with all the necessary information for the correct use of your SA80 Air
Quality Monitor.
Health Disclaimer

While the SA80 can detect levels of airborne particulates it cannot
determine the health impact for any given individual. Respiratory ailments
and allergic symptoms are caused by a variety of factors. The SA80 is not
meant to be used in the treatment or mitigation of any medical condition.
Please consult your physician

Display with All Elements Shown in below figure.
Trend Icons
The icon indicates that the reading is on the rise. The icon
indicates that the reading is declining.
Air Quality Icons
There are faces icons showing the current air quality. They indicate Good,
Normal, and Harm air quality respectively. See Table 1 for the criteria of
judgment.

In one line, all 3 criteria need to be met at the same time. For example, for
Good air quality : CO2<800 ppm, and PM2.5 <12 µg/m3, and PM10
<50 µg/m3.
Installation
Install the SA80 at a location and height in the room where you want to
test the air quality. Be aware that particulate concentrations and CO2
concentration can vary dramatically from one location to another within
the same house.
Materials Supplied
1. Monitor
2. DC 5V 0.5~2A Adapter
3. Operation manual
THEORY OF OPERATION
Theory of CO2 Measurement: SA80 uses Dual Beam Non-dispersive
infrared (NDIR) principle to detect the existence of CO2 in the air.

Automatic Background Calibration (ABC) is disabled.
Theory of PM2.5 and PM10 Measurement: SA80 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.
OPERATION
Power On
The monitor is powered by an adaptor (5VDC/0.5~2A output).
Plug in the adaptor and the monitor turns on automatically with a short
beep. The monitor will warm up briefly and the reading will be displayed.
Levels are updated every 2 seconds.
The display will shows the CO2 (ppm or %), PM2.5 concentration reading
(PM2.5 g/m3), PM10 concentration reading (PM2.5 g/m3), Temperature
reading (°C or °F), Humidity reading (%RH).
In the condition of operating environment change, it takes 2 minutes to
respond for CO2 sensor, 10 sec for PM2.5/PM10 sensor and 30 minutes
for RH.
For the most accurate measurement, do not place the monitor close to
any source of CO2.
Note:
Failure to use the correct power configuration will damage the monitor.
Note:
Do not hold the monitor close to faces in case that exhalation affects CO2
levels.
Note:
Air Sampling Port: Always ensures that the monitor air sampling inlet and
outlet port are not blocked and open to the atmosphere.

Button Operation
1. Fahrenheit and Celsius switching Button
Press Fahrenheit and Celsius switching button to select two temperature
units (℃and ℉).
2. Minimum and Maximum Readings
The monitor automatically records minimum and maximum CO2 levels. To
view the minimum and maximum readings while in Normal Display:
1) Press MAX/MIN button to display the maximum reading.
The symbol is displayed.
2) Press MAX/MIN button again to display the minimum reading.
The symbol is displayed.
3) Press MAX/MIN button to return to Normal Display.
To reset the minimum and maximum readings:
1) With the minimum or maximum reading displayed, press MAX/MIN
button for 2 seconds.
2) “Clr” will display and the monitor will return to Normal Display.
Note:
When LCD backlight is off, press any button to turn on the backlight before
operation.
LCD backlight will turn off automatically after 60 seconds of button
inactivity.
Ambient Calibration (400ppm) for CO2
This monitor can implement CO2 ambient calibration when needed (such
as annually). Place the monitor in the window ventilation and charged,
then press Fahrenheit and Celsius switching button for 5 seconds until
"CAL" appears. The monitor enters the CO2 ambient calibration (400ppm).
