Silica Exposure Measurement for Construction tsi.com

Silica Exposure Measurement Instruments Do TSI instruments measure total respirable silica? Not directly. TSI instruments use light stering photometric technology to measure the amount of total respirable dust in the air. When properly calibrated, the instrument can determine the amount of crystalline silica in the aerosol sample.
