Labtron Air Quality Monitor LAQM-B19

Air Quality Monitor LAQM-B19 – Multi-Parameter Indoor Air Quality Monitor
Air Quality Monitor LAQM-B19 is a multi-parameter indoor air quality monitoring device that measures CO₂, PM2.5, PM10, VOCs, formaldehyde, temperature, and humidity. It provides real-time monitoring with AQI display and fast sampling to help laboratories, offices, and classrooms assess air quality and maintain safe indoor environments.

What is LAQM-B19?
LAQM-B19 is an indoor environmental monitoring instrument designed to detect both airborne particles and gaseous pollutants. It helps evaluate indoor air safety, ventilation efficiency, and pollutant exposure in enclosed environments.

What Does LAQM-B19 Measure?

Carbon dioxide (CO₂)
Particulate matter (PM2.5, PM10)
Formaldehyde (HCHO)
Total volatile organic compounds (TVOC)
Temperature
Humidity
Air Quality Index (AQI)

What Is AQI and Why Is It Important?
AQI (Air Quality Index) converts multiple pollutant readings into a single value, making it easier to understand overall air quality and potential health risks.

Why Monitor VOCs and Formaldehyde?
VOCs and formaldehyde are common indoor pollutants from chemicals, furniture, and lab materials. Monitoring them helps detect exposure risks and maintain safe indoor environments.

Where Is LAQM-B19 Used?

Laboratories and research facilities
Classrooms and educational institutions
Offices and indoor workplaces
Healthcare and clinical environments

How Does LAQM-B19 Work?

The monitor uses:

NDIR sensors for CO₂
Laser scattering for particulate matter
Semiconductor sensors for VOCs and formaldehyde

It continuously samples air and updates readings all ~1.5 seconds for real-time monitoring.

Key Features

Multi-parameter pollutant detection
Real-time monitoring (1.5 sec updates)
AQI display for simplified interpretation
Portable with rechargeable battery
USB-C continuous operation
Compact design for wall or desktop use
