Selecting Turbidity Units - LaMotte 2020t/i Mode D'emploi

SELECTING TURBIDITY UNITS

The results for each calibration curve will be reported in the default units for that
calibration curve unless diff erent units are chosen. The default unit is shown after the
calibration curve name. The default units are:
Calibration Curve
2020t Nephelometric
Ratiometric
Attenuation
2020i Nephelometric
Ratiometric
Attenuation
It is possible to choose to have the results reported in an alternative unit instead of the
default unit for each mode. When ASBC (American Society of Brewing Chemists) and EBC
(European Brewery Convention) units are desired the Nephelometric calibration curve
should be used.
For the 2020t, the available units are: NTU, NTRU, AU, ASBC, EBC
For the 2020i, the available units are: FNU, NTU, FNRU, FAU, ASBC, EBC
NTRU, AU, FNU, FNRU and FAU are numerically equivalent to NTU. The units diff erentiate
which detector and light source was used to make the measurement. See page 12 for the
defi nition of turbidity units.
