Silica Exposure Measurement for Construction TSI

Silica Exposure Measurement for Construction TSI

The photometric calibration factor adjusts the photometric reading of the instrument to the known silica content in the dust. This allows the instrument to display a representative level of respirable silica exposure (to a worker) that is very close to what one would expect from a gravimetric sample.
