TE-5028 Air Sampler Calibrator    Get Quote

Tisch Environmental high volume air sampler are used for the calibration of high volume air samplers. These calibrators are manufactured out of high quality aluminum to ensure maximum reliability and consistency. To provide the most accurate instrument possible, these devices are calibrated by our highly trained technicians in our NIST traceable calibration lab.  Learn More

TE-HVC X-Calibrator High Volume Calibrator    Get Quote

The Tisch Environmental X-calibrator high volume calibrator is a highly accurate and reliable device for the calibration of PM10, PM2.5, TSP, and industrial hygiene high volume air samplers. Featuring an LCD display, this instrument is attached to the sampler and instantaneously displays the ambient flow rate. The X-Calibrator uses integrated barometric pressure and ambient temperature sensors to accurately calculate the ambient flow rate. Manual flow rate calculations and spreadsheets are no longer necessary with the Tisch Environmental X-Calibrator.  Learn More
