What is Labmate LMAQM-A122? 

Indoor Air Quality Monitor LMAQM-A122 is a portable device that measures indoor air pollutants including PM1.0, PM2.5, PM10, CO₂, TVOC, temperature, humidity, and AQI. It provides real-time environmental readings to help monitor indoor air safety in homes, offices, laboratories, and industrial spaces.

What does Labmate LMAQM-A122 do?

It continuously tracks indoor air quality by measuring particles, gases, and climate conditions. The device helps identify pollution levels, ventilation issues (CO₂ buildup), and indoor environmental changes in real time.

Who should use Labmate LMAQM-A122?

• Offices and corporate buildings

• Schools and classrooms

• Laboratories and research facilities

• Industrial indoor environments

• Homes requiring CO₂ monitoring

What is CO₂ monitoring? 

CO₂ (carbon dioxide) in indoor environments indicates ventilation efficiency.

• Normal range: ~400–1000 ppm

• Above 1000 ppm: poor ventilation

• Above 2000 ppm: fatigue, discomfort risk

High CO₂ levels usually mean insufficient fresh air exchange.

How Labmate LMAQM-A122 Works 

Air enters the device and passes through sensors:

• Laser scattering detects particulate matter (PM)

• NDIR infrared sensor measures CO₂ concentration

• Semiconductor sensor detects VOC gases

• Internal system calculates AQI in real time

Results are shown instantly on the display.

What is AQI?

AQI (Air Quality Index) is a scale from 0–500:

• 0–50: Good air quality

• 51–100: Moderate

• 101–200: Poor

• 200+: Unhealthy air

What happens when CO₂ is high?

• Indicates poor ventilation

• May cause fatigue or reduced focus

• System: increase airflow or ventilation

• Use air circulation or fresh air exchange

How to use Labmate LMAQM-A122

1. Place device at breathing height

2. Avoid placing near vents or windows

3. Turn on device

4. Wait 2–3 minutes for stabilization

5. Read CO₂, PM, and AQI values

6. Adjust ventilation if readings are high
