The personalDataRAM (pDR-1000AN) measures mass concentrations of dust, smoke, mists, and fumes in real time, and sounds 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. Highest performance of any real-time personal particulate monitor - High correlation with gravimetric measurement - Simple zeroing and calibration - Indoor air quality monitoring - Personal exposure monitoring - Emergency response

Measures Airborne Particulates Concentration in Real Time
With conventional air quality monitoring methods, you won't find out until tomorrow that you have reached dangerous levels or are out of compliance today. In contrast, the personal DataRAMTM alerts you to a problem within seconds and allows you to take immediate corrective action. It stores this information in detail for subsequent retrieval / printout / graphing via a computer.
The world's smallest and most versatile direct reading personal aerosol monitor, the personalDataRAM 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. Any tag can store up to 13,000 averages plus tag maximum and STEL values. When you begin a run, the instrument automatically tags and time stamps the data collected.
Highest Performance of Any Real-Time Personal Particulate Monitor
With a measurement range from 0.001 to 400 mg/m3 (auto-ranging), an optically feedback-stabilized sensing system, ultra-low power consumption, and rigid all-metal construction, the personalDataRAM sets new standards for sensitivity, long-term stability, and reliability. These capabilities allow its use in many applications where such compact monitors were previously considered unsuited.
Easy to Read Two-Line Display
The personalDataRAM's two-line LCD readout continuously displays both real-time and time averaged (TWA) concentration values, updated every second. Other screens are easily selected by scrolling through a simple user-friendly menu. Self-diagnostics continually monitor the unit's operation and flag any problems. LCD screens indicate remaining memory, battery status, optical background level, as well as any electronic malfunctions may also be selected.
Only four tactile-feedback keys (including On-Off) are required to perform all operations and commands, such as enable / disable logging and alarms, review of program parameters, and review of maximum / STEL data.
How Real Time Aerosol Monitors Work
Extremely Compact and Rugged Design
Palm-sized, the pDR-1000AN weighs only 1/2 kilogram (18 ounces). The unit can be attached to a belt or shoulder strap, hand-held, operated on a table top, or mounted on a tripod.
The personalDataRAM's rugged, yet attractive, brushed aluminum case is designed to protect the unit's optics and electronics in even the harshest industrial environments. Heavy-duty molded bumpers shield the monitor from inadvertent mishandling and moderate impact. The absence of any moving parts (e.g., pumps, motors, valves, etc.) and the use of low-power semiconductor components throughout ensures long life and failure-free operation.
Sensing Principle Achieves High Correlation with Gravimetric Measurements
The personalDataRAM is a light-scattering photometer (i.e., nephelometer) that incorporates 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 45o to 90o by the airborne particles passing through the sensing chamber is linearly proportional to their concentration.
The personalDataRAM's optical configuration produces optimal volume response to particles in the size range of 0.1 to 10µm, achieving high correlation with standard gravimetric measurements of the respirable and thoracic fractions.
Passive Air Sampling is Silent and Reliable
The personalDataRAM's passive air sampling technique has been thoroughly field-proven since 1980. Air surrounding the monitor circulates freely through the open sensing chamber by natural convection, diffusion, and background air motion. With this passive nephelometer sampling method, concentration measurements do not depend on the air velocity through the sensing chamber.
Easy Programming and Downloading with a Computer
The personalDataRAM is easily programmed from any IBM-compatible personal computer. Using the pDR-COM software provided with the unit, operating parameters such as logging period, display averaging time, alarm level, and mode can be modified. With logging enabled, the unit automatically tags and time stamps the data collected, then stores the data for subsequent retrieval / printout / graphing. The personalDataRAM retains the setup information until the next.
Using the pDR-COM software, logged data can be downloaded to a PC for direct tabular and graphic display, and/or printout. The data can be imported into most common spreadsheet programs by following the instructions provided.
Simple Zeroing and Calibration
Each personalDataRAM comes gravimetrically calibrated (NIST-traceable) in mg/m3 using standard SAE fine (ISO fine) test dust. Zeroing with particle free air is accomplished quickly and effectively under field conditions using the zeroing kit (included). Special firmware controls an automatic calibration check referenced to the optical background set at the factory. Gravimetric field calibration can be performed by comparison with a filter sampler and by programming of the calibration constant.
Unlike typical particle counting devices, the personalDataRAM is totally immune to particle coincidence errors, even at the highest concentrations. For exposure sampling or continuous unattended indoor air, ambient, duct, or process monitoring, no other aerosol monitor is as fast, accurate and easy to use as the personalDataRAM. This significantly advanced model is an improvement over the previous version, DR-2000, by the addition of many features such as internal self monitoring, features to increase sensitivity especially with new fine aerosol monitoring regulations and easier to use software and display to mention a few.
