Thermo Scientific pDR-1000

The world’s smallest and most versatile direct reading personal aerosol monitor, the Thermo Scientifc pDR 1000 (personal DataRAM) measures mass concentrations of dust, smoke, mists, and fumes in real-time, and sounds an on-board audible alarm whenever a user-defined level is exceeded. Integral large-capacity data logging capability permits storage of 13,000 data points in up to 99 discrete tags.

Applications: 

Indoor air quality monitoring

Walk-through surveys

Personal exposure monitoring

Time & motion studies

Workplace & plant monitoring

Remediation personal surveillance

Mobile monitoring in vehicles & aircraft

Toxicology & epidemiology studies

Emergency response

Testing air filtration efficiency

Features: 

Light-scattering photometer offers high correlation with gravimetric measurement of respirable and thoracic fractions with optimal response to 0.1-10μm size particles

Datalogger automatically tags and time stamps data collected and stores it for subsequent retrieval, printing, or graphing through a PC

No moving parts means silent operation and minimal maintenance costs

Unit is gravimetrically calibrated in mg/m and is ready to use after easy zeroing step (kit included)

Internal firmware controls automatic calibration check; gravimetric calibration can be performed in the field for maximum efficiency
