Factors Affecting Air Quality
 |
PM2.5 (Particulate Matter 2.5) refers to fine particles with a 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 particles 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 is normally considered as less harmful to health than PM2.5. |
 |
CO2 (Carbon dioxide) is a colorless and odorless gas that is 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. |
Important!
- Do not place the detector in highly polluted environments (concentration of CO2>2500ppm or particle>500pg/m3) for a long time to avoid damage to the sensor.
- Do not cover the air inlet/outlet during detection, or let fluff or hair enter the detector.
- Do not use the detector in humid environments with a strong odor.
- Do not make contact with organic solvents, such as glue/adhesives/paint/alcohol, etc.
- If the battery level shows 0, please charge the detector promptly to avoid effects during use (also chargeable when turned off).

Operation
Warning!
- First use or unused for a long time: Please put it outside for over 6 hours for calibration.

Operation: Press or button to adjust the value and press to switch digits. Then press Save to save the setting and exit the interface, or press Exit to exit without saving the setting (See the figure below).
e. Calibration zero: Calibrate the sensor to zero (no such function for PM2.5 interface). Take CO2 interface below for example:
f. EXIT: Exit the current interface.
View all info
The View all info interface displays all the detected data including the concentration of PM2.5, PM10, CO2, number of particles, temperature and humidity. Press to switch between °C and °F. See the figures below.
Press to pause or detect; press sr 
to back to the main menu interface.
History
The History interface includes Storage interval and Data export functions (See the figure below).
Operation: Press or to switch between Storage interval and Data export, then press to enter the corresponding interface.
a. Storage interval: Press:to switch between digits, Save and Exit. When you select a digit, press or to adjust the value to your desired storage interval among 1, 5, 10, 30, and 60 minutes, then locate the option to Save and press to save the setting and exit the interface; or locate the option to Exit and press to exit the interface without saving the setting.
b. Data export: In this interface, you will see the following tips.
If connected to the computer successfully by the USB cable, the detector will pop up a tip USB connection successfully; If not, it will remind you of the failure (See the figures below).
After connecting successfully, the detector will generate in the computer a removable storage device Temtop, which contains a folder named History. The history folder includes a CSV format file listing the date and time, PM2.5, PM10, and CO2 concentration (see the figure). Please save it to your computer for viewing.
| Date | PM2.5 | PM10 | Co2 | |
| 2019/10/28 15:5 | 6 | 10 | 2038 | |
| 2019/10/28 15:10 | 7 | 11 | 1795 | |
| 2019/10/28 15:15 | 8 | 14 | 1914 | |
After the data is copied and viewed, please press to exit and restart the detector (See the figure below).
Set
The Set interface displays 5 options below. Operation: Press or to select the desired option; press to enter the interface.
a. Date and time: Allows customized setting of year, month, date, and time (See the figure below).
Operation: Press orto adjust time and press to switch to the next digit. Then press to switch to Save or Exit. Press to finish the settings and exit the interface.
b. Alarm value: Set a high alarm limit for PM2.S, or CO2 concentration (See the figure below).
Operation: Press or set a high alarm limit for PM2.S, or CO2 concentration, and press to switch to the next digit. Then press to switch to Save or Exit. Pressto finishes the settings and exit the interface.
c. Help: View the help information for using the detector (See the figure below).

FAQ:
Q: Why is the data reading very high/over-range after the detector is turned ON?
A: As being packed in ink printed package box over time may interfere with the sensor due to the remaining organic volatile residue inside the package. Therefore, after unpacking, please put the detector in a ventilated place to help accelerate its data recovery.
Q: Why is data reading unstable?
A: As airflow in the environment is changing, the distribution of organic matter concentration may be uneven. Temp recommends trying again in low airflow areas.
Q: Why is the test result abnormal or below normal?
A: (1) Please check whether the air inlet or outlet has been covered or fluid is in.
(2) Gently shake the detector during detection to increase the interaction with the surrounding air.
(3) The sensor maybe not have recovered. Please place the detector outdoors for ventilation.
Q: Can the calibration be accelerated if the detector is facing the outlet of air conditioner/fan?
A: No. The temperature difference or airflow speed at the air conditioner/fan outlet is relatively high, which may cause condensation or temperature changes on the sensor, affecting its detection performance. Please put the detector outdoors in a cool ventilated place.
Q: Why is the PM2.5 reading constantly changing?
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 and etc. but also due to common pollutant sources like smoking, cooking; exhaust emissions from vehicles, smoke from burning coal/chimneys/furnaces and etc. All of these may influence the PM2.5 concentrations and give differences in the readings.
Q: Which reference standards have been used to indicate the pollution levels?
A: Reference Standards for Particles and CO: are shown below.
| Status/ Pollutant | Good | Moderate | Unhealthy for Sensitive Groups |
Unhealthy | Very Unhealthy |
Hazardous |
| PM2.5 (pg/m3) |
≤12 | 12.1∼35.4 | 35.5∼55.4 | 55.5∼150.4 | 150.5∼250.4 | ≥250S |
