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.
2 Incontrast, the pDR-1000AN alertsyou to a problem within seconds,allowing you to take immediateaction. 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.
3 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. The intensity of the lightscattered over the forward angle of50oto 90oby airborne particlespassing through the sensingchamber is linearly proportional totheir concentration.
4 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.

6 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 )
7 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. 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.
