SOFTWARE
NANOCHECK
The 32-bit GRIMM Windows software
for NANO devices features an intuitive
user interface to control the instruments
as simple as possible. It comes with a
built-in tutorial, electronic version of the
manual, and powerful utilities for data
handling.
During the measurements, corrections for
diffusion losses and activation efficiency
are applied in real-time. The state-of-the-art
data reduction algorithms were developed
by Professor Reischl, Institute of Physics,
Vienna University.
The software supports on-line logging of
data and instrument parameters with
display as graph or as table. The particle
number distribution can be converted to
surface area distribution, volume distribution,
and if the density of the aerosol
particles is known, to mass distribution.
The data is easily exported for further
analysis.

Personal Exposure Monitor
The NanoCheck is a portable personal exposure
monitor for continuous indoor and
outdoor measurements of nanoparticles.
Typical sources of nanoparticles are cooking,
smoking, laser printers, fires, and traffic.
It provides total number concentration
for particles between 30 nm and 300 nm
along with the mean particle diameter.

In combination with a GRIMM optical
spectrometer, it records ambient aerosols
from 30 nm to >30 micrometer in up to 32
channels.
The NanoCheck combines an unipolar
electrical diffusion charger, a time multiplexed
conductivity measurement, and a
Faraday Cup electrometer for measurements
with a time resolution of 10
seconds. It needs no consumables.
