Limitations of Use
This instrument is designed for titrating liquids,
observing the following physical limits:
– use temperature from +15 °C to +40 °C (from
59 °F to 104 °F) of instrument and reagent
– vapor pressure up to 500 mbar
– viscosity up to 500 mm
– altitude: max. 3000 m above sea-level
– relative air humidity: 20% to 90%
Operating Limitations
Chlorinated and fluorinated hydrocarbons or chemi-
cal combinations which form deposits may make
the piston difficult to move or may cause jamming.
When working with crystallizing solutions follow
cleaning instructions (see pages 54 - 57).
Compatibility of the instrument for this special
application (e.g., trace material analysis) must be
checked by the user or contact the manufacturer.
Battery Specifications
2 micro-batteries, 1.5 V (AAA/UM4/LR03),
non-rechargeable.
Recommended Application Range
The instrument can be used for the following titration media (max. conc. 1 mol/l):
Reagent
Acetic acid
Alcoholic potassium hydroxide
solution
Ammonium iron (II) sulfate solution
Ammonium thiocyanate solution
Barium chloride solution
Bromide bromate solution
Cerium (IV) sulfate solution
EDTA solution
Hydrochloric acid

Operating Exclusions
Never use this instrument for
– liquids attacking borosilicate glass, Al
PFA, FEP, PTFE or platinum-iridium (e.g.,
hydrofluoric acid)
– suspensions (e.g., of charcoal) as solid particles
may clog or damage the instrument
– concentrated acids and bases as well as non-
polar solvents which effect swelling of plastics
(e.g., Toluene, Benzene)
– Carbon disulfide, as this media is highly
flammable
– The instrument must not be autoclaved!
– The instrument should not be used in an aggres-
sive atmosphere (e.g., HCl fumes).
Storage Conditions
Store the instrument and accessories only in
cleaned condition in a dry place.
Storage temperature: from -20 °C to +50 °C
(-4 °F to 122°F), relative air humidity: 5% to 95%.
