A. Product Overview

The Temtop M100 2nd Air Quality Monitor is an indoor environmental monitoring device designed to measure multiple air quality parameters including PM2.5, PM10, CO2, TVOC, temperature, humidity, and AQI.

It features a 7-inch touch screen display, WiFi connectivity, and supports data visualization through real-time values and historical curve graphs (daily and monthly).

The device provides reference ranges for different parameters to help users understand whether the environment is good, fair, or poor, based on pollutant levels and comfort conditions.

It also supports multi-device integration, allowing connection with sub-devices for monitoring multiple locations.

B. Working Principle

The device works by continuously detecting and analyzing different indoor air quality parameters using built-in sensors:

• PM2.5 & PM10: Detect particulate matter in the air based on particle size (≤2.5 µm and ≤10 µm respectively).
• CO2: Measures concentration of carbon dioxide generated mainly from human respiration to assess ventilation levels.
• TVOC: Detects volatile organic compounds by responding to changes in indoor chemical intensity on a defined scale.
• Temperature & Humidity: Monitors environmental comfort and conditions affecting health and air quality.

The system processes these inputs to display:

• Real-time values
• AQI (Air Quality Index) based on PM2.5 and PM10
• Historical trend graphs (daily/monthly)

The device also allows calibration of sensors to maintain measurement accuracy when deviations occur.

C. Why It Is Used

The device is used to monitor indoor air quality conditions and identify environmental risks:

• High PM2.5 exposure can lead to respiratory and cardiovascular issues.
• Elevated CO2 levels indicate poor ventilation and can cause drowsiness, dizziness, and reduced concentration.
• Increased TVOC levels indicate presence of chemical pollutants from household or indoor sources.
• Improper temperature and humidity can affect comfort, health, and promote growth of pollutants like mold and bacteria.

The device helps users:

• Understand indoor air quality levels
• Identify pollution sources
• Take corrective actions such as improving ventilation
• Monitor trends over time

D. Suitable Buyers

Based on usage and features described in the manual:

• Users needing indoor air quality monitoring
• Individuals monitoring health and environmental conditions
• Users requiring multi-room monitoring with sub-devices
• Users needing data tracking and historical analysis
• Environments where continuous air monitoring is required

The device is suitable for indoor environments where air quality needs to be observed and maintained.

E. FAQ

Q1. What parameters does the Temtop M100 2nd measure?

It measures PM2.5, PM10, CO2, TVOC, temperature, humidity, and calculates AQI based on particulate matter.

Q2. Why are measured values different from official AQI data?

The device measures air quality at its specific location, while official data is an average from multiple monitoring points.

Q3. Why can CO2 readings be high?

High CO2 levels may occur due to poor ventilation. It is recommended to place the device in a ventilated area or perform calibration.

Q4. What is TVOC and its common sources?

TVOC refers to volatile organic compounds from sources like paints, cleaning supplies, furniture, and household products.

Q5. Why are TVOC readings high after unpacking?

Packaging materials may release organic compounds that temporarily affect readings. Ventilation helps stabilize the values.

Q6. Can the device display historical data?

Yes, it provides daily and monthly data curve graphs for trend analysis.

Q7. Does the device require calibration?

Calibration is recommended before first use or when measurement deviation exceeds acceptable limits.
