RespiDigit : For the simultaneous measurement of dust fractions

RespiDigit TM

RespiDigit TM2

Fine-dust concentrations still pose a significant hazard in workplace atmospheres. This motivated the drastic reduction of TRGS 900 concentration limits in 2014 and, thus, necessitates dust monitors with increased sensitivities.
In cooperation with the German Institute of Workplace Safety (IFA, Sankt Augustin) and the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM, Hanover), Hund has developed the combined gravimetric-photometric dust monitor RespiDigit TM2 which meets the higher sensitivity demands.
For the measurement of higher dust concentrations, the RespiDigit TM is available.
The online dust monitor RespiDigit TM2 is an attractive alternative to purely gravimetric systems. These may deliver precise results, their evaluation, however, is time-consuming and sophisticated.
Which specifications do RespiDigit TM/ RespiDigit 2 TM meet?

The separation characteristics of the three stages correspond to EN 481 – which makes the instrument a model for the separation characteristics of the human respiratory tract.
Thus, the RespiDigit TM has been a proven tool for workplace monitoring for years. With higher sensitivity and sampling flow rate, the RespiDigit 2 TM facilitates the measurement of even small mass concentrations in accordance with the new limits as documented in TRGS 900.

How does the RespiDigit TM/RespiDigit 2 TM work?

The RespiDigit TM and RespiDigit 2 TM contains three internal stages, separated by virtual impactors.
Each of the three stages carries a filter on which the respective dust fraction is collected. After gravimetric determination of the collected dust masses, the included evaluation software calculates the concentrations of the inhalable, thoracic and respirable dust fractions. In addition, the included scattered-light photometers provide time-resolvedconcentration measurements.
