Thank you for purchasing a Halogen Moisture Analyzer from METTLER TOLEDO.
Your Moisture Analyzer is fast and reliable. It offers a high level of operating convenience and useful
functions to facilitate determination of the moisture content of your samples.
Behind your instrument stands METTLER TOLEDO, a leading manufacturer of not only balances and
scales for the lab and production, but also analytical measuring instruments. A customer service net
work covering the entire globe with well trained personnel is your service at all times, whether you are
choosing accessories or require guidance for a specific application to ensure optimum utilization of
your instrument.
Your Halogen Moisture Analyzer is used for determining the moisture content of almost any substance.
The instrument works on the thermogravimetric principle. At the start of the measurement the Moisture
Analyzer determines the weight of the sample, the sample is then quickly heated by the integral halo
gen heating module and the moisture vaporizes. During the drying process the instrument continually
measures the weight of the sample and displays the reduction in moisture. Once drying has been
completed, the moisture or solids content of your sample is displayed as the final result.
Of decisive importance in practice is the rate of heating and even heating of the surface of the sample.
In comparison with conventional infrared heating or the drying oven method, for example, the halogen
heating module of your instrument needs a shorter time to reach its maximum heating power. It also
allows use of high temperatures, an additional factor in shortening the drying time. Uniform heating of
the sample material ensures good repeatability of the drying results and makes it possible to use a
smaller amount of sample.
The instrument has a CE declaration of conformity and METTLER TOLEDO as the manufacturer has
been awarded ISO 9001 and ISO 14001 certification. This provides you with the assurance that your
capital investment is protected in the long term by a high product quality and a comprehensive service
package (repairs, maintenance, servicing, adjustment service).

2.2Product Specific Safety Notes
General Safety Information
Your instrument meets the state of the art technology and complies with all recognized safety rules,
however, certain hazards may arise in extraneous circumstances. Do not open the housing of the
instrument: It does not contain any parts which can be maintained, repaired or replaced by the user. If
you ever have problems with your instrument, contact your authorized METTLER TOLEDO dealer or ser
vice representative.
Always operate and use your instrument only in accordance with the instructions contained in this
manual. The instructions for setting up your new instrument must be strictly observed.
If the instrument is not used according to these Operating Instructions, protection of the instru
ment may be impaired and METTLER TOLEDO assumes no liability.
Intended Use
Your Moisture Analyzer is used for determining the moisture in samples. Use the instrument exclusively
for this purposes. Any other type of use and operation beyond the limits of technical specifications
without written consent from Mettler-Toledo AG, is considered as not intended.
Moisture determination applications must be optimized and validated by the user according to local
regulations. Application-specific data provided by METTLER TOLEDO is intended for guidance only.
6 Safety Information
It is not permitted to use the instrument in explosive atmosphere of gases, steam, fog,
dust and flammable dust (hazardous environments).
Staff Safety
The Moisture Analyzer may be operated only by trained personnel who are familiar with the properties
of the samples used and with the handling of the instrument.
In order to use the instrument, you must have read and understood the operating instructions. Keep
the operating instructions for further reference.
Never make any modifications to the instrument and use only original spare parts and optional equip
ment from METTLER TOLEDO.
Protective Clothing
It is advisable to wear protective clothing in the laboratory when working with the instrument.
A lab coat should be worn.
A suitable eye protection such as goggles should be worn.
Use appropriate gloves when handling chemicals or hazardous substances, checking
their integrity before use.
Safety Notes
WARNING
Risk of electric shock
Your instrument is supplied with a 3-pin power cable with an equipment
grounding conductor. Only extension cables which meet this relevant stan
dards and also have an equipment grounding conductor may be used. Inten
tional disconnection of the equipment grounding conductor is prohibited.
7Safety Information
CAUTION
The Halogen Moisture Analyzer works with heat!
a) Ensure sufficient free space around the instrument to avoid heat accumu
lation and overheating (approx. 1 m free space above the heating mod
ule).
b) The vent over the sample must never be covered, plugged, taped over or
tampered with in any other way.
c) Do not place any combustible materials on, under or next to the instru
ment since the area around the heating module may be hot.
d) Exercise caution when removing the sample. The sample itself, the sample
chamber, the draft shield and any sample vessels used may still be very
hot.
e) During operation, you should never open the heating module itself as the
ring-shaped heating reflector or its protective glass can reach 400 °C! If
you have to open the heating module e.g. for maintenance, disconnect the
instrument from the power supply and wait until the heating module has
cooled down completely.
f) No modifications must be made within the heating module. It is particular
ly dangerous to bend any components or remove them or to make any
other changes.
Certain samples require special care!
With certain types of samples, there is a possibility of danger to personnel or damage of property.
Please note that the user always has the responsibility and liability for damage caused by use of any
types of samples!
CAUTION
Fire or Explosion
• Flammable or explosive substances.
• Substances containing solvents.
• Substances which evolve flammable or explosive gases or vapors when
heated.
a) In cases of doubt, perform a careful risk analysis.
b) Work at a drying temperature that is low enough to prevent the formation
of flames or an explosion.
c) Wear protective goggles.
d) Work with small amounts of sample.
e) Never leave the instrument unattended!
8 Safety Information
WARNING
Substances which contain toxic or caustic components
Toxic gases produced during drying could cause irritations (eyes, Skin, breath
ing), illness or death.
– Such substances may be dried only in a fume cupboard.
CAUTION
Corrosion
Substances which evolve corrosive vapors when heated (e.g. acids).
– Work with small amounts of samples as the vapor can condense on cool
er housing parts and cause corrosion.
