1 Product OverviewAnalyze Detect Measure ControlTMpersonalDataRAM SeriesMeasures airborne particulate concentra-tion in real time pDR-1000 ANFor passive air sampling applications pDR-1200 For active air samplingapplicationsAll these applicationsin one small unit Indoor air qualitymonitoring Walk-through surveys Personal exposuremonitoring Time &motion studies Workplace &plantmonitoring Fixed-point continuous monitoring Remediation personalsurveillance Remote alarming Mobile monitoring invehicles & aircraft Toxicology &epidemiology studies Emergency response Testing air filtrationefficiencyMeasure airborneparticulate concentration inreal-timeThe personalDataRAM(pDR-1000AN) measures massconcentrations of dust, smoke,mists, and fumes in real time, andsounds an audible alarm wheneverthe user-defined level is filter-based monitoringmethods cannot indicatedangerous, real-time dust levels. Incontrast, the pDR-1000AN alertsyou to a problem within seconds,allowing you to take immediateaction.

2 With the dataloggingenabled, the instrumentautomatically tags and time stampsthe data collected, and stores it forsubsequent retrieval, printing, orgraphing through a performance of any real-time personal particulate monitorWith a measurement range to 400 mg/m3(auto-ranging),and an optical feedback stabilizedsensing system, the pDR-1000 ANsets the standard for sensitivity,long-term stability and palm-sized pDR-1000 ANweighs only 18 oz ( kg) for easyportability and attachment to a beltor a shoulder strap. The absenceof any moving parts, such aspumps, motors and valves, and theuse of low-power semiconductorshoused in a ruggedized caseensures long life and correlation with gravimetricmeasurementThe pDR-1000AN is a light-scattering photometer( , nephelometer) incorporating apulsed, high output, near-infraredlight emitting diode source, a silicondetector/hybrid preamplifier, andcollimating optics and a sourcereference feedback PINsilicondetector.

3 The intensity of the lightscattered over the forward angle of50oto 90oby airborne particlespassing through the sensingchamber is linearly proportional totheir concentration. This opticalconfiguration produces optimalresponse to particles in the sizerange of m, achieving highcorrelation with standardgravimetric measurements of therespirable and thoracic zeroing and calibrationThe pDR-1000AN arrivespractically ready to use after theeasy zeroing step. The unit comesgravimetrically calibrated in mg/m3(NIST traceable) using standardSAE Fine test dust (ISOFine).Zeroing with particle-free air isaccomplished quickly andeffectively under field conditionsusing the zeroing kit included withthe instrument. Internal firmwarecontrols an automatic calibrationcheck. To maximize efficiency inthe field, gravimetric calibration canbe performed by comparison with afilter sampler and programming ofthe calibration SeriesFeatures and Technical SpecificationspDR-1000 ANHand-held and fixed-point, real-time aerosol monitor/dataloggerStandard Accessories Universal voltage power supply PCcommunications software Zeroing kit Belt clip kit Instruction manual Carrying case Signal output cablesOptional Accessories Rechargeable battery pack (NiMH) Active sampling kit (convertspDR-1000AN to pDR-1200) Portable pump unit Shoulder strap Remote alarm interface Wall mounting bracketDesigned for activeparticulate monitoringapplicationsThe personalDataRam (modelpDR-1200) performs activesampling applications and aerosolsizing.

4 The pDR-1200 requires avacuum pump module to performparticle size selectivemeasurements under fieldconditions. The separate pump (notincluded) is required for activesampling and aerosol sizing. Withoptional inlet accessories, thepDR-1200 is excellent for ambientair measurements under variablewind and high humidity is ideal for respirable, thoracic,and monitoring, as well ascontinuous emission and testchamber monitoring. With anisokinetic sampling set, thepDR-1200 can beused for stack andduct extractivesampling filters canbe used to captureparticles for particlesfor subsequentlaboratory sizingThe pDR-1200incorporates anoptimally designedmetal cyclone (BGIM odel GK ) or theoptional low flowcyclone (BGI ModelTriplex ) especiallyselected for at operating the pump at specificsampling flow rates, the pDR-1200cyclone preseparator providesprecisely defined particle size calibration and particlesamples by filter collectionAn integral filter holder directlydownstream of the photometricsensing stage accepts 37 mmfilters.

5 The calibration constant ofthe pDR-1200 is simply adjusted tocoincide with the filter-determinedconcentration. Primary gravimetriccalibration of the instrumentconcentration readout is easilyaccomplished under actual fieldconditions by means of this integralfilter.
