Information about the device

Functional description
The particle counter is designed to measure the size and
amount of particles in the air. The detected data can be used for
analysing cleanrooms or prove environmental burdens from
particulates.
To detect the data, the particle counter sucks in air for an
adjustable amount of time and determines the size and amount
of particles contained in it.
Particles of the sizes 0.3 μm, 0.5 μm, 1.0 μm, 2.5 μm, 5.0 μm
and 10.0 μm are treated equally during this process.
There are three methods of analysis (see also Definitions):
Cumulative: Amount of all particles up to the selected particle
sizes, e.g.: 0.5 μm = 417 means that 417 ppm
of the particles have a size of > 0.3 μm to
0.5 μm.
Differential: Absolute concentration of the different particle
sizes per channel and measured volume.
Concentratio Averaged concentration of the different particle
n: sizes per channel per measured volume.
The detected values for all active particle sizes are displayed on
the 2.8 inch colour display simultaneously. In addition, the air
burden in one particle size selected by the user is displayed on
a colour indication scale. As soon as the particle burden is no
longer in the green area of this scale, a beep is emitted (see
table Alarm limit values for particle burdens).
In addition to the counted particles, the temperature and relative
humidity as well as the dew point and wet-bulb temperature
calculated from that information are displayed. Measurements
as well as the associated photo and video documentation can
be saved in the internal memory of the device or on a microSD
card, and then transmitted onto a PC via USB cable.
The device is equipped with an integrated measuring cell with
laser (class 3R laser, 780 nm, 1.5-3 mW). Owing to the tamper-
proof enclosure it is classified as laser class 1 (DIN EN 60825-1)
according to the Technical Regulations of the Occupational
Health and Safety Ordinance on Artificial Optical
Radiation (TROS) devised by the German Federal Institute for
Occupational Health and Safety. Maintenance and repair work
may only be carried out by trained expert staff observing the
legal regulations.

The limit value ranges listed for the respective channel were
determined on the basis of ISO 14644-1 and in connection with
practical experience values. They are in no way legally binding
and have a merely orientating function.
