For Improved Data Security
The new combined liquid standard reference materials from METTLER
TOLEDO reduce uncertainty, eliminate time-consuming and error-prone
sample transfer and facilitate fully automatic performance verification.
No manual handling –
No errors due to contamination
The combined standard reference material comes in
vials suitable to be used directly on the SC1 and SC30
automation units – no syringe required. This not only
reduces effort but also eliminates errors due to con-
tamination.
Two parameters in one –
Fewer standard reference materials required
The four new combined standard reference substances
are certified for density value and refractive index at
three different temperatures. They can therefore be used
to certify or verify both, density and refractive index
instruments. Users of DR Combined Meters benefit
greatly as they can verify the two measuring cells in
one simple step.
Barcode certificates –
Simple and effective verification procedure
All the information contained in the certificates of the
combined standard reference material is coded in one
single barcode. Users of LiQC systems simply scan
this barcode and let the system perform the subsequent
processes – no need to input data manually!
