Information about the device
Device description
The measuring device allows to easily and quickly monitor the
air quality with respect to the content of formaldehyde(HCHO)
and volatile organic compounds (TVOC).
Furthermore, a MAX/MIN function and a HOLD function are
available for assessment of the measurements.
The measuring device comes equipped with a selectable display
illumination.
When not in use, an automatic switch-off saves the battery.
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/category1B and
Germ cell mutagenic/category2 with effect from 1January
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!

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.

Operation
Inserting the battery
Insert the supplied battery before first use.
Note
Make sure that the surface of the device is dry and the
device is switched off.
1. Open the battery compartment at the rear of the device by
sliding down the cover in the direction of the arrow.
2. Use the battery clip to connect the 9V battery with correct
polarity.
3. Place the battery with the battery clip into the battery
compartment.
4. Slide the cover back onto the battery compartment until it
locks in place.
Switching the device on
Info
Note that moving from a cold area to a warm area can
lead to condensation forming on the device's circuit
board. This physical and unavoidable effect can falsify
the measurement. In this case, the display shows
either no measured values or they are incorrect. Wait a
few minutes until the device has become adjusted to
the changed conditions before carrying out a
measurement.
1. Take the device out of the packaging so that it can adapt
to the climatic and chemical ambient conditions. This way
the measurement is not affected by substances possibly
contained in the packaging material.
2. Press the Power button(8) for approx. 2s.
ð The device switches on.
3. Wait for approx.90s until the TVOC sensor is ready for
use. This is indicated by a countdown from 90 to 00 on the
display for the TVOC measured value(15).
Carrying out a measurement
1. Point the sensor(1) at the desired measuring range or the
measuring environment to be examined.
2. Wait until the displayed value has stabilized. This process
may take a few minutes depending, among other things,
on whether the device has just been switched on or has
already been operated for some time.
3. Read the HCHO value from measured value display(16)
and the TVOC value from measured value display(15).
Changing the unit PPM / mg/m
3
If required, you can change the unit. When doing so, please
observe the following conversion factor for HCHO and TVOC:
1ppm=1.226mg/m3.
1. Press the SET button(6) to change the displayed unit.
HOLD function
1. Press the Lamp button(5).
ð The HOLD indication(11) appears on the display.
ð The current value will be held.
2. Press the Lamp button(5) again.
ð The HOLD indication (11) disappears.
ð The display again indicates the current measured value.

MAX/MIN function
Li-Ion
By use of the MAX/MIN function you can either read the highest
or the lowest value of the current measurement interval.
1. Press the MAX/MIN button(7).
ð The MAX indication(12) appears on the display.
ð The display now shows the highest HCHO and TVOC
values measured since the device was switched on.
2. Press the MAX/MIN button(7) again.
ð The MIN indication(13) appears on the display.
ð The display now shows the lowest HCHO and TVOC
values measured since the device was switched on.
3. Press the MAX/MIN button(7) again to return to the realtime measured value display.
Switching on the display illumination
ü The measuring device is switched on.
1. Press the Lamp button(5) for approx. 3s and let go of it
again.
ð The display illumination goes on.
2. Press the Lamp button(5) for approx. 3s once again and
let go of it again.
ð The display illumination switches off.
Automatic switch-off
If the indication for automatic switch-off(10) is displayed, the
device will switch off automatically when not in use for approx.
15 minutes.
To deactivate automatic switch-off, please proceed as follows:
ü The measuring device is switched on.
1. Press the Power button(8) for approx. 3s.
ð The indication for automatic switch-off(10) disappears.
ð Automatic switch-off is deactivated.
Repeat these steps to switch automatic switch-off back on.
Switch-off
If the automatic switch-off function(10) is activated, the device
will switch off after approx. 15 minutes of non-use.
1. Press the Power button(8).
ð The device is switched off.
ð The MAX and MIN values are reset.
