Factory 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 beabsorbed 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.

HCHO (Formaldehyde) is a colorless and strongsmelling 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.

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 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 airquality 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, O3, SO2, NO2, CO etc. Temtop follows EPA Standards to calculate and focus only for AQI of PM2.5&10.

Important!

• 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/m3 or PM concentration above 500ug/m3 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.

Buttons

Press and hold the button for 2 seconds in the main display of “PM2.5, AQI, HCHO” to enter the system settings.

Power Saving (Example Of Button Operation):

Press the or button to scroll up or down and press the button to confirm.
Press the or button to switch to the item you want to set.
Press the or button to increase or decrease the current value.
Then press the or button to switch to save or exit, and press button to save the setting or exit the interface.

2. ” Screen Off (min) ” : The screen will automatically switch off after 30 minutes.
3. The “Backlight Level” are divided into 0, 1, 2, 3, 4 and 5.

Calibration
In this interface, you will you can see figure below.

HCHO Calibration
Press the or button to switch to the “Calibration zero” and press button to calibrate.

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.

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”

PM2.5 Calibration
You can calibrate the PM2.5 value by adjusting the “K” factor

Formula :
K(target value) = PM2.5(target value) / PM2.5(current value) * K(current value).

Example：
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”.

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 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.

• For LKC-1000S 2nd /LKC-1000S+ 2nd Only.

If connected to the computer successfully by the USB cable, the detector will pop up a tip USB connection successful; If not, it will remind you of the failure (See the figures below).

After successful connection, the detector creates a removable storage device “TEMTOP” on the computer, which contains a folder named “HISTORY”. This history folder contains a history file named after the time, e.g. “20230601”. The history file is in CSV format and lists information such as date, PM2.5, PM10, PARTICLES, AQI, HCHO, TVOC, Temperature, Humidity, etc. (see figure below).

FAQ

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 differences 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 affect 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 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 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.

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.
