6.1 Buret data
The 807 Dosing Unit is equipped with a data chip which contains the
specifications for the dosing unit, the tubing connections and the reagent
used. The data chip can be read and overwritten by an 800 Dosino.
Indications on dosing unit / tubing connections
￭ Order number of the dosing unit
￭ Serial number of the dosing unit
￭ Serial number of the dosing cylinder
￭ Length and diameter of the tubings on the dosing ports
￭ Validation date
￭ etc.
Indications on the reagent
￭ Name of the reagent
￭ Titer of the reagent
￭ Concentration of the reagent
￭ Production and expiry date of the reagent
￭ etc
The 807 Dosing Unit makes it possible to read and overwrite data with the
aid of a suitable device (e.g. Titrando). Consult the respective manual in
order to determine whether the Metrohm device which you are using is
capable of accomplishing this. The contact surfaces for data exchange
with the data chip are made of titanium and are exceptionally resistant to
both chemicals and abrasion.
CAUTION
Take care to ensure that the contact surfaces do not become contami-
nated. Wipe off any contaminations at once. In the event of more seri-
ous contamination, the underside of the 807 Dosing Unit can be
cleaned with a moist cloth (possibly with a small amount of dishwash-
ing detergent or ethanol).
