METTLER TOLEDO DE40/50/51 Density Meter 77
14.5 Coke (Cola drinks)
This Memory Card allows to measure BRIX and HFCS42 (also called SOLIDS) of all Cola
products, from beverages to the highly viscous syrup (concentrate). This card includes
viscosity correction, required for syrup measurement and specially tuned up for Cola
products. This viscosity correction is especially required for products over 40°BRIX (resp.
50°SOLIDS).
14.6 Coefficients for conversion to various concentration data
With all software you can convert the measured density directly to Baumé, Twadell, API or
milk degrees:
In the Calc.Para menu select <Result>, <Conc.>, <Parameter Set>, <Coefficient>. Then:
– select the relative density d
t
4
or d
t
t
– select the term for the x-axis under Data Replace,
– select A + Bx as calculation function,
– enter the coefficients A and B under Manu Set.
The “Conc” value is printed out as the result in each case.
