The particle counter “Abakus? mobil air” is an evaluation system for measuring the number and size of

particles in air and in gaseous media. The measuring system is suitable for stationary as well as mobile

use. By default the device is delivered with a sensor LDS 328 (additional sensors see table). These

include monitoring and checking of clean rooms, clean benches, filter facilities in operation rooms, filling

facilities in the pharmaceutical industry, separation efficiency determination of filters. The simple menuprompting

feature enables an efficient way of working from the start. During the measurement, the LCD

display gives you the overview of 32 particle size channels, date, time and the number of the running

measurement. The measuring results are represented as a table. After the end of measurement, a thermal

printer enables you to print out the data together with threshold value exceedings and sample

identification. With the software “Log and Show“, you can do further processing of the measuring results at

the PC; the software also allows direct measuring and archiving. The automatic calibrating function of the

particle counter enables an easy checking and recalibration of the system.
