Binder KBF 720 (E5.2) - Intended Use

KBF / KBF P (E5.2) 02/2012 page 16/103
1.6 Intended use
Climatic chambers series KBF / KBF P are suitable for exact conditioning of harmless materials. A mixture
of any component of the charging material with air must NOT be explosive. The operating temperature
must lie below the flash point or below the sublimation point of the charging material.
Following the instructions in this operating manual and conducting regular maintenance work
(chap. 16) are part of the intended use.
DANGER
Explosion hazard.
Danger of death.
∅ Do NOT introduce any substance combustible or explosive at working temperature into
the climatic chamber.
∅ NO explosive dust or air-solvent mixture in the inner chamber.
The charging material shall not contain any corrosive ingredients that may damage the ma-
chine components made of stainless steel, aluminum, and copper. Such ingredients include in
particular acids and halides. Any corrosive damage caused by such ingredients is excluded
from liability by BINDER GmbH.
1.7 Resistance of the humidity sensor against harmful substances
The following list of harmful substances refers only to the humidity sensor and does not include any other
materials incorporated in the unit or prohibited substances in relation to explosion protection.
Some gases - especially clean gases - do not have any influence on the humidity sensor. Others do have
a very small influence, whereas others may influence the sensor to a larger extent.
• The following gases do not influence the sensor and the humidity measurement: Argon (Ar), carbon
dioxide (CO
