Special Feature

Design as  per Indian standard BIS 5182 (Part 23)  : 2006, digital flow indicator & volume totalizer, waterless  manometer eliminate  filling  of  distilled  water  and  maintaining  zero  level  in  glass manometer  tube. Electronic  flow  controller,  Sampling  flow  will  maintain  the  pre  set  level  even during  filter  chocking,  ampere  and  voltage  variation,  instrument  will  auto  shut  if  flow  vary  from set flow & time limit. Brushless, regenerative, belt less,100 % oil free, almost maintenance free & zero consumable noise less turbine blower

Flow rate

Free flow more than 1.5 m3/min without filter paper and with flow stabilization is disable. 1.0m3/min with filter paper installed and flow stabilization controller enabled

Particulate Sampling

10  micron  down  to  0.1  micron  (depending upon  type  of  filter  used). A  cyclone  is  used  for fractionating  the  dust  into  two  fractions, D-50 cut off for  the  cyclone  is  at  10  microns.  RSPM  is accumulated  on  the  filter  paper  (8X10 inch  size)  while  coarse  dust  is  collected  in  a  cup  placed  under the cyclone.

Digital Manometer

Digital display of manometer flow on 16 characters, 2 line LCD display. Flow indication in two digit with 3  decimal  places  &  volume  tantalization indication in  five  digit  with  2  decimal  place.  Auto Zero of Volume by pressing single key.

Time Recorder

0 to 99999.99 hrs. time totalizer records the running time in hours

Clock / Timer

Programmable Real Time control system with control of automatic start & stop, number of required intervals can be programmed, Timer is used to start and shut off the sampler at preset time

Sampling

24-28 hr.

Blower

Brushless/Noise less

Power requirement

Nominal 220 V, Single Phase, 50Hz AC mains supply.
