Labtron Air Quality Monitors provide quick and efficient detection of various gases, temperature, humidity, and other parameters. These can detect a wide range of pollutants including fine particulate matter, larger particulate matter, volatile organic compounds, carbon dioxide, and more. They ensure complete monitoring of indoor and outdoor air quality. They store past air quality readings for trend analysis and comparison. Our Air Quality Monitor offers a battery-powered option for flexible and portable usage.








The monitor should be placed in a well-ventilated area, away from direct sunlight and sources of heat or humidity, to ensure accurate readings. Additionally, avoid placing it near open windows or vents. For optimal performance, place it at breathing height in the room, ideally around 1 to 1.5 meters off the ground. This placement helps capture air quality representative of the space's typical conditions.
Yes, the alarm threshold for CO? levels can be adjusted via the settings menu or mobile app, depending on the model. One can customize the thresholds based on specific requirements or safety guidelines for environment. This flexibility allows setting different alarm levels for various spaces or situations, ensuring that the monitor alerts when air quality reaches critical levels.
The monitor typically takes a few minutes to stabilize and start providing accurate readings once powered on. This brief warm-up period allows the sensors to calibrate properly, ensuring that the readings reflect the true air quality. During this time, the monitor may display initial fluctuations in the CO? levels before stabilizing.
The monitor uses laser scattering technology to accurately detect particulate matter (PM2.5, PM10) levels in real-time. This method ensures high precision in measuring dust and other fine particles in the air, providing reliable data for air quality management. It helps in identifying pollution sources and can aid in taking corrective actions to maintain a healthy indoor environment.
Yes, the monitor is designed to operate effectively in environments with humidity levels ranging from 20% to 85%. This makes it suitable for a wide range of indoor spaces, including offices, factories, and homes, ensuring reliable performance even in humid conditions. The device's accurate measurement capabilities remain consistent in varying environmental conditions, allowing for optimal Multi-Functional Air Quality Monitoring.
Air quality monitor is an important tool for improving air quality, protecting public health, and ensuring compliance with regulations. It can also be used to monitor climate change or support research and development.
Our air quality monitor can detect particulate matter (PM 2.5, PM 10), carbon monoxide, ozone, nitrogen dioxide, sulphur dioxide, volatile organic compounds.
Place the air quality monitor in an area with good airflow and don’t obstruct the air intake vent. For optimal sensor readings, keep your device away from direct sunlight and in open space that’s less than 500 square feet. Avoid placing your device near air vents, such as an AC or heater vent.
Our air quality monitor is ideally suited for use in homes, offices, industrial settings, and outdoor monitoring.
Air quality monitor is a device that measures the level of common air pollutants including both tiny and large particulate matter. They provide quick and efficient detection of various gases, temperature, humidity, and other parameters. Our air quality monitor ensure complete monitoring of indoor and outdoor air quality.
