AirSafe PM

Preferred Communication Method
This field is for validation purposes and should be left unchanged.


The new AirSafe PM provides continuous and precise monitoring of dust exposures in indoor ambient air.



  • Continuous measurement of PM levels used to monitor workforce exposure to PM
  • Provides data to Health and Safety to help to comply with the maximum recommended exposure values
  • Reporting tools with user friendly interface and real-time measurements


Proving Particulate Matter Sizing

Monitoring and understanding PM sizing is important to ensure a safer working environment. The AirSafe PM is a powerful tool to help you minimise worker exposure risk and optimise your process with dust control systems.


How Does it Work?

The AirSafe PM uses a high end optical measurement system that is embedded in the sensor. The air flows through the measuring device which counts
the particles and defines their size. The raw measurement is processed by a unique algorithm which enables continuous and accurate measurement for the different sizes of particles as well as classification of inhalable and respirable fractions.


Measuring Ranges for the AirSafe PM

  • PM1
  • PM2.5
  • PM4.25
  • PM10
  • TSP


Where is the AirSafe PM installed?

The AirSafe PM is designed to be used indoors only. It can be installed in any room that needs particulate monitoring as part of exposure and health safety limit monitoring.

  • Cement plants
  • Foundries
  • Incineration plants
  • Wood workshops
Install the AirSafe PM as near as possible to areas of static air/settlement where people work.
Health and safety personnel can use the measurement data to provide a safe working environment and report site air quality.



The AirSafe PM WIFI version includes wireless communication and the ENVEA interface eSAM. This interface allows the user to see measurements in real-time, display recorded measurement of a selected time frame and download data. It is a great tool to generate elements of exposure reports.
As the sensor is designed to be used in process areas, it has a 4-20 mA active output to be connected to any PLC. It has a relay output and Modbus communication.
Wireless (WLAN) communication allows the user to connect to the sensor using any device, such as PC or a tablet



Ceramic Tile Manufacturing

A ceramic tile manufacturer that is aware of the health issues related to PM, wants to continuously monitor the level of exposure to PM to its workforce.
Currently, the only solution is an annual check by a third party company using portable equipment. This gives them an onetime indication of the concentration levels of PM in the ambient air, but it is not a viable long-term solution to drive down exposure.
The AirSafe PM provides continuous measurement of PM of different sizes (PM1, PM2.5, PM4.25, PM10 and TSP) and can classify them as A or E dust fractions according to EN 481. This allows to check that the short term (15 mins) and long term (8hours) exposure levels are being respected.
In the event that the levels are exceeded, the data can be analysed in conjunction with production data to identify the source and the company can take proactive measures to improve working conditions.
