PM2.5 (Particulate Matter 2.5) refers to fine particles with a diameter of 2.5
microns or less. Due to its tiny size, PM2.5 can get absorbed into the bloodstream
and lungs, so long-term exposure to high levels of PM2.5 may cause eye and
nose irritation, coughing, asthma, emphysema, lung disease, heart attacks,
cancer, and more.
PM10 (Particulate Matter 10) relates to particulate matter with a diameter of
10 microns or less. Due to its larger particle size, PM10 can be inhaled and does
not penetrate the bronchial tubes because larger particles can be made available
by the cilia and mucus in the nose and throat. It is usually considered less of a
health hazard than PM2.5.
Carbon dioxide(CO2) is a colorless and odorless gas usually derived from the breath
of humans and animals. High CO2 concentration means that fresh air or ventilation
is required; otherwise, it may cause problems such as drowsiness, dizziness, loss
of attention, and cognitive impairment.
TVOC (Total Volatile Organic Compounds) are a wide range of chemicals that readily
evaporate into the air at room temperature. TVOC sensors behave similarly to the
human nose, responding to changes in the relative intensity of indoor TVOCs on
a scale from 1 to 500.

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 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 PM2.5, PM10, O
3, SO2,
NO
2, CO etc. Temtop follows EPA Standards to calculate and focus only for
AQI of PM2.5&10.

Important
★ To ensure accurate measurements, do not use the detector for extended periods
in humid environments or those with strong pungent odors.
★ Do not cover the vents of the detector and keep lint out of the detector, as the
particle sensor may not work correctly.
★ Do not come into contact with organic solvents, which include silica gel and other
adhesives, paintings, drugs, oil, and high-concentration gases.
★ To ensure optimal communication performance, please avoid placing the device
on metal objects or near thick walls, as metal and thick walls may block signal
transmission.
★ Do not dismantle the unit yourself. In the event of a defect, contact your dealer
instead, who will liaise with the service center and, if necessary, send the device in
for repair.
★ Children should only use this device under adult supervision. Keep packaging
materials, such as plastic bags and plastic wrap, out of the reach of children as they
present a choking hazard.
★ This product can help monitor the health of the indoor environment, but should
not be used as a professional measurement tool.
★ Due to the upgrade and update of the product program, the actual operation
interface may dier slightly from the description in this manual. Please refer to the
actual operation interface of the product for accuracy.

Calibration example (PM2.5)
● Use the numeric keypad to set the target value you intend to calibrate, then click OK
to confirm.
● Click Calibrate to start the calibration process. If successful: A "Calibration Successful"
prompt will appear. If failed: A "Calibration failed" prompt will be displayed.
● After calibration is completed, click Confirm to return to the previous interface.

Please ensure that the equipment has
been placed in a well-ventilated area
200
Notes:
1) CO2 calibration must be performed in an outdoor fresh air environment (with an approximate
CO2 concentration of 400 ppm). Before calibration, the device shall be kept running stably for 10
minutes and placed at least 1 meter away from crowds.
2) Ensure sucient power supply. Otherwise, the calibration will be terminated due to shutdown
or power failure, resulting in calibration failure, inaccurate data, and the need for re-calibration.

Q: Why can't I receive the verification code when I sign up for an APP account?
A: ①
Please check the advertisement mails and spam mails, your mailbox may automatically.
A: ① classify the CAPTCHA mails into advertisement mails and spam mails.
A: ② Google Mail, Outlook, and other major mailboxes are recommended.
A: ③ You can also log in directly using third-party accounts such as Google or Apple.
Q: Why can't the APP connect to the device?
A: ①
Make sure your phone and device are in the same room and as close to the device as possible.
A: ② Try restarting the device or connecting with another phone.
A: ③
If the issue is still not resolved, please contact our customer service for further support.
Q: Why does the indicator light stay o?
A: As PM2.5 concentration in the environment is changing all the time not only due to
environmental factors like changes in airflow, humidity, wind direction, etc. but also due
to common pollutant sources like smoking, cooking; exhaust emissions from vehicles,
smoke from burning coal/chimneys/ furnaces, etc. All these may influence the PM2.5
concentrations and give dierences in the readings.
FAQ
Q: AQI/ PM2.5/PM10 and other values, why the measured value is inconsistent with
the ocial announcement?
A: The AQI/PM2.5/PM10 shown on the display is a measurement of the space where
the device is located. The measured value published on the Internet or ocial websites
is the average value of several monitoring points, and each measurement point will be
dierent. At the same time, according to the regulations of EPA and WHO, the AQI value
is calculated based on the highest value among the five pollutants in the atmosphere
on that day. In the past ten years, the local AQI in the United States has basically been
calculated with the value of PM2.5/PM10, and sometimes with the value of O
3.
Q: Is it true that AQI calculations are not scientific?
A: We calculate the AQI based on PM2.5/PM10, which is MAX (AQI-PM2.5, AQI-PM10),
and there are corresponding AQIs for O
3, CO, SO2, NO2, and so on, and the ocial one
is released with the maximum of these AQI-PM2.5, AQI-PM10 and other 6 AQIs. The
main source of indoor pollution is particulate matter so AQI-Particulate Matter can
respond well to indoor AQI.
Q: Why is CO
2 data high?
A: The user's environment may be poorly ventilated,resulting in high CO
2 concentration;
it is recommended that the user place the product in an outdoor ventilated place for 10
minutes. If the data is still high, the customer is advised to perform a CO
2 calibration
via the APP.
24
Q: What is TVOC and what are the common sources in households?
A: TVOC (Total Volatile Organic Compounds) refers to a variety of chemical substances
that easily evaporate into the air at room temperature. The TVOC sensor behaves
similarly to the human nose and reflects changes in the relative intensity of indoor
TVOC on a scale from 1 to 500. Common sources of TVOCs in the home include alcohol,
air fresheners, citrus fruits, scented candles, paints, cleaning supplies, pesticides, building
materials and furniture, inks, glues, and various cosmetics.
Q: Why are the TVOC data readings very high/out of range when with the detectors on?
A: Being packed in an ink-printed box may interfere with the sensor over time due to
the organic volatiles left in the packaging. Therefore, once unpacked, please place the
detector in a ventilated area to help speed up its data recovery.
