Labmate LMAQM-A120 vs LMAQM-A110

• A120: Includes ozone (O₃) + PM + VOC monitoring

• A110: Focused on CO₂ and formaldehyde

• A120 advantage: broader gas detection coverage for environmental assessment

Limitations

• Does not measure CO₂ concentration

• Not designed for outdoor meteorological analysis

• Requires proper placement for stable accuracy

Maintenance & Calibration

• Clean air inlet periodically to avoid dust blockage

• Calibration recommended based on usage intensity

• Avoid placing near vents or direct emission sources

• Stable indoor airflow improves measurement accuracy
