英文详细介绍description portability:the2ha is the smallest, lightest analog photometer available inaportable self-contained unit. the 2ha has been designed withtheuser in mind for simplicity of operation andvirtuallymaintenance-free use. its basic purpose is to detect andmeasuremass concentration of aerosol in air technology: a stream ofcleanair from an ulpa filter is passed through the forwardlightscattering chamber as the instrument is balanced electricallywithrespect to any incidental straylight or dark current. a baselineof response may be set as a basis of comparison, using theinternalreference circuit, which is set for 100 microgramsofpoly-dispersed particles. once the base line has been set,anysubsequent reading will be in relation to that base line. therangeof concentration measurable is from 100 to 0.0001 on 5linearscales on the standard instrument. the 2ha has twopre-setreference values (dop & pao) for aerosol agents. theoperatorcan quickly select dop or pao as the challenge aerosol.featuresthe 2ha photometer is furnished in a rugged, die castaluminum casethat is suitable for use in industrial or laboratoryenvironments.the unit is equipped with a switching internal powersupply toenable operation on all standard electric currentworldwide. 2hanthe 2ha is also available in a version suitable fornuclearapplications, the 2han. this unit has features identical tothe 2haplus a special sealed sampling chamber and hepa filter tominimizecontamination of internal components. the unit isspecificallydesigned to allow safe removal and replacement ofcontaminatedsampling components.scanning probe
the optional scanning probe has a analog display thatissimultaneously updated with the 2ha display. this featureenablesan operator to pinpoint leaks and accurately determine %leakage ata location remote from the unit. a flexible, segmented,tubelocated between the handle and sampling nozzle allows thenozzle tobe adjusted to any angle necessary to scan a filtersurfaceefficiently. three interchangeable nozzles are provided tomeetindustry standards and protocols and permit fast,accuratescanning.shipping case: an optional heavy-duty,lockableshipping case is also available. this highly recommendedcase islined with a thick poly-foam cushioning and meets therequirementsof all commercial carriers for shipping or as carry-onluggage. itcan accommodate the 2ha unit, scanning probe withnozzles, 100%sample tubing, operation manual and power cord.
specifications size: 10.1 w × 14.3 d × 5.8 h (25.7 cm w × 36.3cmd × 14.7 cm h weight: 15.5 lbs. plus 2.5 lbs. for scanningprobe& accessories = 18.0 lbs. enclosure: instrument case isrugged,die cast aluminum and can be easily disassembled as requiredforrecalibration and service of internal components. the enclosurehastwo convenient retractable carrying handles on the sides.fold-uplegs under the case can tilt the control panel displayupward foreasy viewing. power: 100 to 250 volts ac, 50/60 hz fusedpowerentry module with spare fuses. automatically adjusts tovirtuallyall standard electric current used worldwide. pleasespecify powersupply cable when ordering unit (ul/csa/vde) alarm:audible alarmin unit sounds when the adjustable set point isexceeded. led onprobe lights up when set point is exceeded.amplifier: solid-statelinear amplifier. accuracy: 2% full-scale forthe decade in use.light source: improved, longer lasting and morestable solid-statescattering chamber light source. photometeroperates at lowerpower, generating less heat and lower straylightvalues. lifeexpectancy is 50,000 to 100,000 hours. scatteringchamber:redesigned smaller, lighter and more efficient forimprovedperformance. easier to clean and requires less maintenance.vacuumpump: true (1) cubic foot per minute (cfm) sample rate (28.3litersper minute) using a twin head, carbon vane pump for quietoperationand dependability. an external exhaust filter can easilybeattached to the outlet of the vacuum pump to entrap anyparticlesfrom the pump exhaust. output: an db9 connector isprovidedstandard on all units for a 0-1 vdc output
