PM2.5 (Particulate Matter 2.5) refers to fine
particles with diameter of 2.5 micrometers
or less. Due to its tiny size, PM2.5 can be
absorbed into bloodstream and the lungs, so
that long-term exposure to high concentration
of PM2.5 environment may cause eye and
nose irritation, cough, asthma, emphysema,
lung disease, heart attacks, cancer and etc.
PM10
(Particulate Matter 10) refers to particulates
with a diameter of 10 micrometers or less. Due
to the larger size, it's inhalable but penetrates
no further than bronchi as larger particles can
be filtered out by cilia and mucus of nose and
throat. It usually considered as less harmful
to health than PM2.5.
TVOC
(Total Volatile Organic Compounds) refers
to various common VOCs including benzene,
toluene, styrene, formaldehyde and etc. Due
to their volatility as well as toxicity, irritability
and carcinogenicity, long-term exposure to
TVOCs can cause damage to the skin, liver,
kidneys,central nervous system and etc.
Temperature & Humidity may often be
ignored however they do have a significant
impact on individual's well-being, comfort,
health and safety as well as your property.
High humidity may lead to an increase in
HCHO
(Formaldehyde) is a colorless and strong-
smelling chemical with formula CH2O or H-CHO,
which has been classified by IARC as Group
1 carcinogen due to its significant dangers to
human health. Long-term exposure to just low
doses could cause chronic respiratory diseases,
nasopharyngeal cancer, colon cancer,brain
tumors,nuclear gene mutations and etc.

household air pollutants especially the
biological contaminants such as molds, bacteria,
viruses and dust mites; cold, low humidity
may cause nosebleeds, skin and respiratory
irritations, dyspnea, static electricity and etc.
AQI
(Air Quality Index) is a quick guide on air
quality levels.It aims to indicates how clean
or polluted the air is in a way that's easy to
understand.It ranges from 0 to 500 that higher
values indicate higher air pollution levels and
more adverse for health.AQI assessment can
indicated for PM
2.5, PM10, O3, SO2, NO2, CO etc.
Temtop follows EPA Standards to calculate and
focus only for AQI of PM2.5&10.
★
It is usual for the detector to show higher values when
first switched on or not used for an extended period.
Please place it in a ventilated area and turn it on for
around 30 minutes before testing.
★ Do not put the detector in an environment with
formaldehyde (HCHO) concentration above 1.0mg/m
3
or PM concentration above 500ug/m
3
for a long time.
Otherwise, the sensor may be damaged and cannot
run normally.
★ Do not come into contact with organic solvents, which
include silica gel and other adhesives, paintings, drugs,
oil and high-concentration gases.
★ Do not use the detector in a humid environment to
maintain detection accuracy.
★ Do not cover the air inlet / outlet when using the
detector.
★ Be cautious of cross interference by ethanol, benzene,
ammonia, etc.

3.2.2 TEMP & HUM Calibration
You can calibrate the temperature and humidity by modifying the
"OFF" value.
Formula :
OFF(TEMP target value) = TEMP(target value) - TEMP(current value) + OFF(TEMP current value).
OFF(HUM target value) = HUM(target value) - HUM(current value) + OFF(HUM current value).
Example：
If TEMP target value is 25.0, current value is 23.0, current value of OFF(TEMP) is -0.2.
Then "OFF(TEMP target value)=25.0-23.0+(-0.2)=+1.8".
If HUM target value is 36.0, current value is 33.0, current value of OFF(HUM) is +1.5.
Then "OFF(HUM target value)=36.0-33.0+(+1.5)=+4.5".
Note:
1. Please ensure that you can calibrate under fresh air outdoors.
2. During the calibration process, please do not perform other operations until the
calibration is successful and you return to the previous level screen.

Note: For products calibrated according to ISO standard, K coecient is 1 by
default. It is only recommended that professional engineers perform this
adjustment under standard conditions with standard laboratory, or test bin
facilities. At the same time, the calibration environment required for P2.5 is
relatively high, and the calibration results will be aected by factors such as
dust/particle size and dierent configurations of standard warehouse
facilities, etc, so it is strongly recommended that you use this function only
under essential conditions or contact us to better support your special needs.

Q: Why data reading is unstable?
A:If the airflow in the current sampling space is in an unstable
state, such as strong wind, the concentration of particulate matter
in the air will be unevenly distributed, and will vary greatly with the
surrounding airflow, resulting in large dierences in measured values.
Q: Why humidifiers can cause rising particulate matter readings?
A: Our sensors use the principle of light scattering. When using a
humidifier, the humidifier will spray many small droplets of water.
Excessive humidity and moisture in the air will cause dust particles
to absorb water and swell, which will aect the scattering of light
and cause deviations in sensor readings.

Q: Why is the data high after booting?
A: The reason why the data is high when you first turn on the
sensor is that when the sensor starts to work, the fan will run
at full speed, and it will take a while (about 1-2 minutes) for
the fan to run stably. At this time, the airflow in the air duct
will be stable, and the data will gradually become stable.
Q: AQI/ PM2.5 and other values, why the measured value is
inconsistent with the ocial announcement?
A: The AQI/PM2.5 shown on the display is a measurement
14
Q: Which the HCHO reading inaccurate or overestimated at
some points?
A: As Temtop uses a high-precision electrochemical HCHO
sensor, its electrochemical reaction characteristics could also
respond to other gases besides formaldehyde.This table lists
the most common gases that interfere with relative sensitivities
of HCHO sensor.

of the space where the device is located. The measured value
published on the Internet or ocial websites is the average

regulations of EPA and WHO, the AQI value is calculated
based on the highest value among the five pollutants in the

in the United States has basically been calculated with the
value of PM2.5/10, and sometimes with the value of O
