Safety measures
– Never work in an environment subject to explosion hazards! The housing of the
apparatus is not gas tight (explosion hazard due to spark formation, corrosion
caused by the ingress of gases).
– Never use reactive gases as a purge gas! They could lead to an explosion.
– Check the gas paths and drying tubes for free gas flow ! This prevents buildup of
an overpressure in the titration cell, which could lead to an explosion.
– Open the stop cock before you stop the gas flow, switch off the apparatus or
lower the temperature ! This prevents siphoning back of the titration solution into
the hot drying oven. Failure to do this could result in an explosion hazard.
– When using chemicals and solvents, comply with the instructions of the producer
and the general lab safety rules!
Measures for operational safety
– Use only fuses of the type specified in the Operating Instructions !
– Have the apparatus opened and serviced only by METTLER TOLEDO service !
– Exclude the following environmental influences:
• powerful vibrations,
• direct sunlight,
• atmospheric humidity greater than 75%,
• temperatures below 5 °C and above 40 °C,
• powerful electric or magnetic fields !
