Calibration Substances
Reference Standards to Verify Instrument Accuracy
Reference standards are substances that enable accurate temperature calibration and adjustment of melting point and dropping point instruments. Each high-purity METTLER TOLEDO calibration substance comes with temperature values that are traceable to primary standards. Calibration substances are provided for the full temperature range for reliable dropping and softening point measurements.

Advantages of Reference Standards
Calibration for Best Performance
With our simple, built-in calibration routines, you can adjust your instrument quickly. Perform a calibration with up to three substances and the instrument automatically calculates the slope and offset values for you.
Accurate Temperature Values
Each METTLER TOLEDO high-purity reference substance comes with temperature values that are traceable to primary standards (LGC, London).
Full Temperature Range
Calibration substances are provided in the range of 40 – 330 °C to cover the full temperature range for reliable dropping and softening point measurements.

FAQs
Which reference substances are suitable to use for calibration and adjustment (performance verification) of a dropping point instrument?
METTLER TOLEDO reference substances such as benzophenone, vanillin, benzoic acid, and potassium nitrate provide certified temperature values that can be used for temperature calibration of the DP70 and DP90 furnaces. Caffeine and saccharine cannot be used as they do not drop properly.
