The device counts the effectively measured particles per separate channel within the set measuring period. There is no averaging as in concentration mode. Measuring in differential mode is therefore more precise. Example: The measuring device shows 100particles in the
0.3μm channel and 30 in the 0.5μm channel. The differential data is 100 particles >0.3μm and <0.5μm, and 30 particles >0.5μm.

Adding up of the measured values per separate channel directly from the first seconds of a measurement. Every second of the running measuring period the device calculates the respective average per channel from the determined values and the resulting volume.
This is a summation of the individual particle sizes in the channel of the next smaller particle size respectively located beneath. Exemplary display:
- 5μ = 26 - 10μ = 14 Then only 12 particles of the size 5μ were measured. 12 + 14 = 26

Examples for carbon monoxide concentration in the air

Examples for carbon monoxide concentrations and their effects:
0 to 1 ppm Normal background levels 9 ppm Max. permissible concentration for interior spaces 35 ppm Max. average amount to which one may be exposed over a
period of 8 hours. * 100 ppm Exposure limit, persons ought to leave enclosed spaces. * 150 ppm Slight headache after 1.5 hours 200 ppm Mild headache, fatigue, nausea and dizziness 400 ppm Frontal headache, life-threatening after 3 hours 800 ppm Dizziness, nausea, convulsions, death within 2 to 3 hours 1600 ppm Nausea within 20 minutes, death within 1 hour 3200 ppm Headache, dizziness and nausea within 5 to 10 minutes.
Death within 25 to 30 minutes. 12800 ppm Death within 1 to 3 minutes * according to OSHA = Occupational Safety & Health Association

Examples for formaldehyde concentration in the air

Formaldehyde is a colourless gas which is often contained in the room air. Depending on the personal sensitivity, it is perceived as a pungent odour above certain concentrations.
Formaldehyde, also referred to as HCHO or methanal, was assigned to the hazard class Carcinogenic/category1B and Germ cell mutagenic/category2 with effect from 1January
2016. Even small quantities of formaldehyde in the room air may affect human health. The consequences include concentration disorders, nervousness, headaches, dizziness, but also nausea, swelling of mucosa, conjunctival irritations and lacrimation. In extremely high concentrations, formaldehyde can cause pneumonia or toxic pulmonary oedema and is therefore fatal.
Moreover, the substance is suspected of having a sensitizing effect on the body with respect to allergies, and of promoting an aggravation of asthmatic symptoms. It is assumed that the adverse health impact of formaldehyde is not caused by the isolated substance but by mixtures of pollutants (VOC/TVOC) containing formaldehyde.
The following specifications serve as guide values, which were determined in international studies. They are not binding since the listed symptoms strongly depend on personal sensitivity!
0.05 to 0.125 ppm Odour threshold
0.01 to 1.6 ppm Irritation of mucous membranes (nose, throat) and
eyes
2.0 to 3.0 ppm Stinging in the nose, eyes, throat
4.0 to 5.0 ppm Bearable for 30 minutes, increasing discomfort,
lacrimation
10.0 to 20.0 ppm Strong lacrimation already after a few minutes of
exposure (lasting for up to 1 hour after exposure), immediate breathlessness, coughing, severe burning in throat, nose and eyes
30 ppm Toxic pulmonary oedema, pneumonia, risk of death!
TVOC – Total Volatile Organic Compounds
Nowadays, interior spaces contain numerous possible sources of volatile organic compounds, so-called VOCs. Such sources include sealants, furniture, varnishes and solvents, insulation material etc.
Every individual volatile organic compound can be associated with specific as well as unspecific health problems. Therefore, there is a maximum limit for the ambient concentration of each of these substances in interior spaces.
Due to the different chemical compositions and the associated different impact potential of each of these substances, an assessment of the overall group of substances is a rather complex issue. However, this is exactly what is tried to be done by way of calculating the sum of the concentrations of these individual compounds, i.e. by determining one collective value, the so-called TVOC value (Total Volatile Organic Compounds).
Owing to the complexity of VOCs, both the individual health effects on the human body and their intensity can be different and vary greatly in certain cases. Therefore, the TVOC concentration and its effects are purely indicative.
Even below the thresholds of an acute individual effect, TVOCs can affect the human well-being and health through so-called combination effects. A long-term exposure to even low TVOC concentrations, particularly to mixtures, can lead to unspecific symptoms and reactions including
perception of unpleasant odours and tastes
runny nose and watery eyes
irritation of eyes, nose, throat
dry mucous membranes and dry skin, itching
increased sensitivity to infections of the respiratory tract as well as
neurotoxic symptoms (fatigue, headaches, reduced mental performance)
and even result in permanent health damage.

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.
Concentration: Averaged concentration of the different particle sizes per
channel per measured volume.

The limit value ranges listed for the respective channel were
1)
Red (signal beep)
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.
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 tamper­proof 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.
