Factors Affecting Air Quality

• 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 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.
• Formaldehyde (HCHO) is a colorless and strong-smelling gas with formula CH20, which has been classified by IARC as Group 1 carcinogen. Long-term exposure to just low doses could cause chronic respiratory diseases, nasopha- ryngeal carcinoma, colon cancer, brain tumors, nuclear gene mutation and etc.

Important!

• Do not place detector in heavily polluted environments for a long time; or it may cause damages to the sensor.
• Do not use the detector in a humid environment to maintain detection accuracy.
• Do not use the detector for a long time in a strong irritating odor environment to ensure measurement accuracy.
• Do not cover the vents of the detector, and do not let fluff enter the detector, otherwise the particle sensor may not work properly.
• Do not disassemble the device. In the event of a defect, please contact your dealer. The dealer will contact the Service Centre and can send the device in to be repaired, if necessary.
• Children should only use the device under adult supervision. Keep packaging material, like plastic bags and plastic film, out of the reach of children, as they pose a choking hazard.
• It is normal for the detector to show higher values when it is first switched on or when it is not used for a long period of time. Place it in a ventilated environment and run it on for at least 0.5 hours before testing. (only for M2000/M2000 2nd).
• Repeat the test at multiple points in the target area to get a more complete picture of your air quality.

   • c. The Calibration interface displays 4 options below (fig.17).

Press or to adjust number and press to switch to next digit. Then press to switch to Save or Exit. Press to finish the calibration and exit the interface (fig.18 & fig.19).

1. PM2.5 Calibration: You can calibrate the temperature and humidity by modifying the “OFF” value.
   • Formula: K(target value) = PM2.5(target value) / PM2.5(current value) * K(current value). Example (fig.18)
   • If PM2.5 target value is 30.0µg/m3, current value is 49.2µg/m3, current value of K is 1.00.
   • Then “K(target value) = 30.0/49.2 * 1.00 = 0.61”
   • For products calibrated according to ISO standard, K coefficient 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 affected by factors such as dust/particle size and different 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.
2. TEMP & HUM Calibration: You can calibrate the PM2.5 value by adjusting the “K” factor.
   • 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 (fig.19)
   • 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”.
   • Press or to stop the calibration and exit the interface(fig.20 & fig.21).If the calibration progress is 100%, the calibration is completed and press or button to exit the interface.
3. CO2 Zero Calibration
4. HCHO Zero Calibration

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.
   • d. Alarm value: Set alarm limit for PM2.5, CO2 or HCHO concentration (fig.22).
   • e. Language : Set Chinese or English as displayed language (fig.23).
   • f . Help : View the help information for using the detector (fig.24).
   • Operation: Press or to view the information that help you use the detector.
   • Press to back to set interface.

FAQ

Why is the PM2.5 reading constantly changing?

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 these may influence the PM2.5 concentrations and give differences in the readings.

Why is the formaldehyde reading inaccurate?

The air is not circulated during storage and transportation. In order to ensure the best performance of the equipment, it needs to be ventilated outdoors for 1-2 hours before the first use. Note that gases such as alcohol, carbon monoxide, and hydrogen sulfide may interfere with the sensor test. Stay away from alcohol, cigarette (including carbon monoxide), soot (including acrolein), and fruit (including ethanol). If the detector is exposed to high concentrations of air pollution, it will damage the sensor and make it unable to work properly.

Why is the test result abnormal or below normal?

Please check whether the air inlet or outlet is covered or liquid has entered. Gently shake the detector during detection to increase the interaction with surrounding air. The sensor may be not recovered, Please place the detector outdoors for ventilation.

Why data reading is unstable?

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 differences in measured values.

Why humidifiers can cause rising particulate matter readings?

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 affect the scattering of light and cause deviations in sensor readings.

Why is the data reading very high/over-range after the detector is turned ON?

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.

Why is the data high after booting?

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.

AQI/ PM2.5 and other values, why the measured value is inconsistent with the fficial announcement?

The AQI/PM2.5 shown on the display is a measurement of the space where the device is located. The measured value published on the Internet or official websites is the average value of several monitoring points, and each measurement point will be different. 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 PM2.5/10, and sometimes with the value of O3.

Which the HCHO reading inaccurate or overestimated at some points?

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.
