2 General information

Always use tablets marked “PHOTOMETER”, never those marked “RAPID”. Do not touch the tablets.
After each measurement, make sure that the cuvette is cleaned from all reagent residues, otherwise measuring errors will occur.
Only use clear water and a microfibre cloth to clean the cuvette.
Do not use any cleaning agents or (scrubbing) brushes.
After using the PHMB reagent, be sure to follow the instructions in section 10.12 PHMB as otherwise, discolouration of the cuvette may occur, which will falsify later measurement results.
The photometers of the PCE-CP series are also suitable for salt water pools / pools with salt electrolysis.

3 System description

3.1 Device

The photometers of the PCE-CP series are suitable for the determination of water quality on the basis of up to thirteen different parameters. The field of application ranges from maintenance and servicing of pool systems to more complex series of measurements in a laboratory environment. For the latter, the automatic storage of measured values which can be read out and documented via a Bluetooth interface using the provided software or app is of particular interest. In order to ensure a correct and error-free measuring procedure, the photometers are equipped with a timer which ensures that the reaction times of the reagents are met before the measurement.

The unit in which the measured values (except pH, alkalinity, total hardness and calcium hardness) are displayed can be switched between mg/l and ppm. The unit in which alkalinity, total hardness and calcium hardness are displayed can be selected from five different options.

1. Light protection cover / measuring chamber
2. Display
3. Membrane keypad

11 Troubleshooting

11.1 OR-UR / dilution

OR = Overrange / UR = Underrange
The test result is outside the measurement range of this method. OR results can be brought into the measurement range by dilution. Use the dispensing pipette to take a 5 ml (or 1 ml) sample. Fill the sample into the cuvette and add 5 ml (9 ml) of distilled water. Perform the measurement and multiply the result by 2 (or 10). Dilution is not applicable to the parameter “pH”.
