Portable smart sensors 

Provide your workers with portable sensors that identify in real time the presence and concentration of crystalline silica on your operations. 


Real-time data transmission via 3G/4G/wifi wireless communication (possibility of storage on SD card)


8-hour battery life to last a full work day on a single charge.


Composed of 2 parts linked with a flexible cable: one positioned close to the respiratory tract which analyses the ambiant air and the main casing containing the battery and the communication systems.


A robust and compact case to resist shocks in a construction site and quarry environment.

Nos solutions

A patented method of identification

Our recognition algorithm based on the spectrophotometry of particles in the air identifies dangerous particles in the air.


Optical measurement of particles in the air and classification according to their size.


Calculation of the respirable fraction based on their sizes.


Identification of the type of dust based on the granulometric signature thanks to the references present in our database.


Calculation of crystalline silica exposure based on the percentage of quartz associated with the recognized dust type.
