Tdesigned to monitor particles as small as 0.3 micron; draws air into sensir at rate of 1 cubic foot per minute; air flow passes through view volume-light generated by laser diode; particles deflect light energy to a solid state photodiode where each burst of light is converted to a pulse of electrical energy; digital counter accumulates the pulses according to size selected; sample air is then filted, removing all particles larger than 0.2 micron before air is exhausted back into room

Selectable size ranges 0.3, 0.5, 1.0, 5, 10 micron and largers (selectable); flow rate 1.0 cfm (0.1 or 0.01 optional); coincidence error 5% at 3, 000, 000 counts; field calibration continuous; factory calibration mono-dispersed polysstryene latex spheres traceable to nist; selectable sample period 0, 1, 6, 10, 60, 600 seconds or infinite; alarm limits 0, 1, 10, 100, 1000, 10, 000, 100, 000; light source solid state laser diode; laser life 20, 000 hours; count display 999, 999; size 12.5 inches wide by 15.0 inches deep by 6.5 inches high; weight 28 lbs; power source 300 watts; voltage 115 vac, 60 hz, 220 vac 50 hz, 100 vac 50/60 hz; 0.3 micron sensitivity; front panel operation; rs-232c or rs-485 parallel centronics
