Warning of explosive substances
Do not expose the battery to temperatures above 60°C!
Do not let the battery come into contact with water or
fire! Avoid direct sunlight and moisture. There is a risk
of explosion!
Warning of laser radiation
Laser class 1
The laser is encapsulated.
Do not open the device to prevent direct contact with
the laser and the emitted radiation!
Warning
Risk of suffocation!
Do not leave the packaging lying around. Children may
use it as a dangerous toy.
Warning
The device is not a toy and does not belong in the
hands of children.
Warning
Dangers can occur at the device when it is used by
untrained people in an unprofessional or improper way!
Observe the personnel qualifications!
Caution
Lithium-ion batteries might catch fire in case of
overheating or damage. Ensure a sufficient distance to
heat sources, do not subject lithium-ion batteries to
direct sunlight and make sure not to damage the
casing. Do not overcharge lithium-ion batteries. Only
use smart chargers that switch off automatically when
the battery is fully charged. Charge lithium-ion
batteries in due time before they are discharged
completely.
Caution
Keep a sufficient distance from heat sources.
Note
To prevent damages to the device, do not expose it to
extreme temperatures, extreme humidity or moisture.
Note
Do not use abrasive cleaners or solvents to clean the
device.
Information about the device
Device 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 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.
Concentration:
Averaged concentration of the different
particle 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.
