Air monitoring system which captures nanoparticles

Clearly verify the presence of dust in production: Companies check the hall air quality efficiently with the new air monitoring system AirWatch.

Kemper GmbH's sensor technology is able to determine and document the number and weight of nanoparticles and then analyze it with smartphone, tablet or PC and compare it to limit values. A traffic light display visualizes permanently the status of air quality. The system is suited for any workplace in production facilities, warehouses and logistics halls. With AirWatch, Kemper wants to raise awareness of the dangers behind fine dust.

“With our new air monitoring system AirWatch, we introduce for the first time a system on the market that is in a position to efficiently measure the number of fine dust particles,” emphasizes Björn Kemper, Managing Director of KEMPER GmbH. For this purpose, the highly sensitive sensor technology is essential as it can capture particles right up to the nano range.

Checks are not depending on the workplace
Whether industrial production facility, warehouse or logistics operation: AirWatch continuously monitors the air quality regardless of the type of workplace. The air monitoring system measures fine dust particles in a radius of up to 30 meters using a laser-powered sensor. An integrated fan draws in ambient air.

It is possible to save individual limit values for hazardous substances. A traffic light shows the current air quality level measured against these values. At the same time, the system saves the data across a long time period. Users access the data simply using a smartphone, tablet or PC. A trend display for day, week, month or year also allows companies to analyze concentration of hazardous substances in more detail.

Verify the presence of fine dust according to WHO standards
AirWatch captures particles in the range of 100 nanometers up to 16 micrometers. This area includes the fine dust categories PM2.5 for alveolar common dust (A dust) and PM10 for all inhalable dusts (E dust) as defined by WHO. AirWatch automatically classifies the captured particles accordingly.

In addition to checking the air quality, AirWatch also monitors the effectiveness of ventilation measures. Companies can independently check their compliance with regulations issued by professional associations apart from official checks made by professional associations.

Highlight the value of employee health
With the system, KEMPER aims to raise awareness of the fine dust risk.

“Companies are wise to continuously check air quality with regards to employee productivity.” Yet, dust in warehouses is also a threat to the quality of products and can develop into a tremendous cost factor.

A best-practice example shows how it is done: Once the Airwatch traffic light jumps to red at the workplace of a metal processor, the employees ask the welder to switch on the extraction and filter plant.

“Not only employees consider their health more thanks to AirWatch,” explains Kemper. Employers show that they consider their employees’ health as important. “Within the framework of a successful recruitment of specialists, they place themselves as a sustainable business.”

Verify hazards despite adherence to limit values
Counting fine dust particles has great advantage compared to applicable limit values, which analyze the weight of fine dust: If coarse dust particles in the production move around then a limit value is surpassed quickly.
Mr Kemper explains that the invisible fine dust on the other hand often remains undetected - with fatal consequences:

“Millions of fine dust particles which do not reach the weight of the specified limit value make employees sick.”

Even if the limit value is adhered to, a permanent exposure to fine dust can lead to serious health problems. Current studies show that fine dust is the cause of increased heart attack risk, accelerates dementia, causes cancer and may even lead to death. The WHO classes fine dust as a direct cause of lung cancer.
