Different forms of representing a measured concentration value that can be
derived from each other.
The method for determining phosphate provides, for example, a measured
value for phosphorous P. This measured value can also be quoted in other
citation forms such as PO4, PO4-P or P2O5.
The detection procedure designates the general principle of how a sample
is brought into a form suitable for measurement.
Different methods can be based on the same detection procedure.
Light Emitting Diode
LEDs are used as the light source in the pHotoFlex
The measured value is the special value of a measured parameter to be de-
termined. It is given as a combination of the numerical value and
unit (e.g. 3 m; 0.5 s; 5.2 A; 373.15 K).
A method comprises a chemical detection procedure and special method
data (calibration line) that are required to evaluate the measurement re-
sults.
How to carry out the method up to the photometric measuring is described
in the analysis instructions.

The pHotoFlex
STD contains a database with methods (programs). Fur-
thermore, user-defined methods can be entered in the database as well.

In the pHotoFlex
STD, methods with the relevant method data are stored
as programs.
Programs are called up via the assigned program number.
Restoring the original condition of all settings of a measuring system.
Smallest difference between two measured values that can be displayed by
a meter.
A test set contains all reagents that are required for the photometric deter-
mination of the sample according to the analysis instructions.
Adjusting a photometer with a water-filled cell.
The zero adjustment applies to measuring all measured parameters (con-
centration, absorbance, transmission) of a photometer.
