This portable dust monitor measures mass concentrations of dust, smoke, mists, and fumes in real time. Passive sampling system for airborne particulate concentration. Audible alarm sounds when user-defined level is exceeded. Stores up to 13000 data points (averages, tag maximums, and STEL) in up to 99 discrete tags.
>All the advantages and functionality of the original personal pDR-1000 plus:
- Unmatched measurement precision and stability
- Ease of programming (using a PC and included software)
- Aerodynamic particle sizing
- Primary calibration and particle samples by filter collection
- Membrane filters of various pore sizes can be used for chemical analysis or for concurrent gravimetric measurement.
The personalDataRAM (pDR-1000AN) measures mass concentrations of dust, smoke, mists, and fumes in real time, and sound an audible alarm whenever the user-defined level is exceeded. Conventional filter based monitoring methods cannot indicate dangerous, real-time dust levels. In contrast, the pDR-1000AN alerts you to a problem within seconds, allowing you to take immediate action. With the datalogging enabled, the instrument automatically tags and time stamps the data collected, and stores it for subsequent retrieval, printing, or graphing through a computer.
With a measurement range from 0.001 to 400 mg/m3 (auto-ranging), and an optical feedback stabilized sensing system, the pDR-1000AN sets the standard for sensitivity, long-term stability and reliability.
The palm-sized pDR-1000AN weighs only 18 oz (0.5 kg) for easy portability and attachment to a belt or a shoulder strap. The absence of any moving parts, such as pumps, motors and valves, and the use of low-power semiconductors housed in a ruggedized case ensures long life and dependable operation. The pDR-1000AN is a light scattering photometer (i.e., nephelometer) incorporating a pulsed, high output, near infrared light emitting diode source, a silicon detector/ hybrid preamplifier, and collimating optics and a source reference feedback PIN silicon detector. The intensity of the light scattered over the forward angle of 50° to 90° 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 μm, achieving high correlation with standard gravimetric measurements of the respirable and thoracic fractions.
The pDR-1000AN arrives practically ready to use after the easy zeroing step. The unit comes gravimetrically calibrated in mg/m3 (NIST traceable) using standard SAE Fine test dust (ISO Fine). Zeroing with particle-free air is accomplished quickly and effectively under field conditions using the zeroing kit included with the instrument. Internal firmware controls an automatic calibration check. To maximize efficiency in the field, gravimetric calibration can be performed by comparison with a filter sampler and programming of the calibration constant.
