The pDR-1000AN personalDataRAM measures mass concentrations of dust, smoke, mists, and fumes in real time, and sounds an audible alarm whenever the user-defined level is exceeded. Filter-based monitoring methods cannot indicate dangerous, real-time dust levels. In contrast, the pDR-1000AN alerts you within seconds, for immediate action. With datalogging enabled, the instrument automatically tags and time stamps the data collected, and stores it for subsequent retrieval, printing, or graphing via computer. The pDR-1000AN is a light-scattering photometer (nephelometer) incorporating a pulsed, high output, near-infrared light emitting diode source, a silicon detector/hybrid preamplifier, collimating optics and a source reference feedback PIN silicon detector. The intensity of the light scattered over the forward angle of 50 to 90 degrees by airborne particles passing through the sensing chamber is linearly proportional to their concentration. This optical configuration produces optimal response to particles in the size range of 0.1-10 um, achieving high correlation with standard gravimetric measurements of the respirable and thoracic fractions. It is gravimetrically calibrated in mg/m3 (NIST traceable) using standard SAE Fine test dust (ISO Fine). Zeroing with particle-free air is quick and effective under field conditions, using the zeroing kit included. Internal firmware controls an automatic calibration check. A rechargeable NiMH battery pack is available as an optional accessory for the pdR-1000AN.
