„ TURBIDITY OPTIONS
Three calibration curves are available: Nephelometric, Ratiometric and Attenuation. For the
2020t BLE, Nephelometric is the default calibration curve and the available units are NTU,
NTRU, ASBC and EBC. For the 2020i BLE, Nephelometric is the default calibration curve and
the available units are FNU, NTU, FNRU, ASBC and EBC for the 2020i BLE.
The 2020t BLE in Nephelometric mode with the default NTU units should be used for
testing public drinking water for compliance with the EPA 180.1 rule.
Once a calibration curve and turbidity units have been selected, they will remain selected
until the calibration curve and turbidity units are changed by performing the following
procedures.
SELECTING A TURBIDITY CALIBRATION CURVE
Three calibration curves are available: Nephelometric, Ratiometric and Attenuation. The
default calibration curve is Nephelometric. The calibration curve should be chosen that suits
the type of sample being tested.

Ratiometric methods typically minimize color interference.
The 2020t BLE in Nephelometric mode with the default NTU units should be used for
testing public drinking water for compliance with the EPA 180.1 rule.
The Nephelometric mode will be used in the example. To change the calibration curve:
