1.1 General features
The compact pHotoFlex®Turb handheld precision meter enables you to car-
ry out the following measurements quickly and reliably:
Photometric measurements
– Concentration measurements (colorimetric measurements)
– Absorbance measurements
– Transmission measurements
pH measurements
Turbidity measurements.
The pHotoFlex®Turb handheld meter provides the maximum degree of ease
of use, reliability and measuring certainty for all applications.
The proven MultiCal® calibration procedure supports you in calibrating for pH
measurements, and the AutoRead function enables precise pH measure-
ments.

1.5 LabStation (optional)
The LabStation, which is available as an accessory, enables you to use the
pHotoFlex®Turb conveniently in the laboratory (see LabStation operating
manual).
Laboratory operation with the LabStation enables the following additional
functions:
With photometric measurements, the zero measurement is retained even
after switching the pHotoFlex®Turb off and on again
You can connect a barcode reader for the simplified calling up of programs
The LSdata software included serves to easily enter user-defined pro-
grams
Operation with power pack and battery pack (included in the scope of de-
livery of the LabStation). The accumulator pack in the pHotoFlex®Turb is
automatically charged as soon as the meter is placed in the LabStation.
