E-SAMPLERDual TechnologyThe E-SAMPLER is a dualtechnology instrument thatcombines the unequalled real-time measurement of lightscatter with the accuracy stan-dard of filter methods. Thesimple filter loading processtestifies to the seamless blend-ing of both technologies.Filters can be extracted andreplaced in less than oneminute and filter medium canbe selected based on laborato-ry analysis. Particulate loadingon the filter does not reduceperformance due to the MetOne actual flow control proto-col. Ambient temperature andpressure are measured andactual flow is calculated andcontrolled by the E-SAMPLERmicroprocessor independent offilter loading change.
PrincipleThe E-SAMPLER providesreal-time particulate measure-ment through near-forwardlight scattering. An internalrotary vane pump draws air at2 LPM into the sensing cham-ber where it passes throughvisible laser light. Aerosols inthe air scatter light in propor-tion to the particulate load inthe air. Scattered light is col-lected by precise glass opticsand focused on a PIN diode.Rugged state of the art elec-tronics measure the intensityof the focused light and outputa signal to the CPU. The out-put is linear to concentrationsgreater than 65,000 ug/m3.Every E-SAMPLER is factory

used in adverse environ-ments without performancedegradation. Even in harshconditions the E-SAMPLERwill operate to specificationsfor 2 years without need ofrecalibration.
OperationThe E-SAMPLER is rugged,portable and easy to use. Theall aluminum enclosure is notonly rugged but provides elec-tronic stability by filteringpotential RF interference. Set-up is a snap with the quickconnect system which workswith the EX-905 tripod. Forother mounting applications,holes are provided to fasten toany structure. Simply turningthe monitor on will start a sam-ple using the most recentparameters. The unit will con-tinue to operate until userintervention or battery failure.Auto-Zero and Auto-Spanensure that the data collectedwill be of the highest quality.Both Zero and Span can beoperated manually or individu-

calibrated using polystyrenelatex spheres of known indexof refraction and diameter atmultiple points to validate lin-earity.
MaintenanceEach E-SAMPLER has twointernal filters (not the 47mmAnalysis Filter) to protect sen-sitive optics and prevent dam-age to the flow components.Both filters are accessible from
ally programmed at varyingtime bases (15 minutes to 24hours). The E-SAMPLER canalso be configured forstart/stop times, recording peri-ods, averaging time and otherparameters.
