Swimming pool Test Background:
Chlorination of water in swimming pools with chlorine or chlorine compounds takes place within certain limits. One distinguishes between free chlorine and bound chlorine (chloroamines); the sum of both is called total chlorine. The content of free chlorine should be between 0.3 and 0.6 mg/L. Chlorination alters the pH value of the swimming pool water. The ideal pH value is pH 7.4. This prevents formation of malodorous pollutants and irritants to the mucous membrane and prevents damage to the water treatment system.
VISOCOLOR ECO Range:
VISOCOLOR ECO presents a product group of colorimetric and titrimetric test kits which avoids hazardous substances wherever possible. With VISOCOLOR ECO even water constituents with low limiting values can be determined with sufficient accuracy. All VISOCOLOR ECO test kits are packed in an environment-friendly box and contain easy to understand instructions in 6 languages. Many of the colorimetric tests can also be used in conjunction with the PF-3 and PF-12 photometers for photometric evaluation of results.

NANOCOLOR Potassium 50 (REF 985045) has been improved. The change is introduced from LOT 45004, which is available from stock as of 20th July 2020.
The test is now produced with an integrated ammonium compensation. The modified recipe allows a simple determination of potassium in the presence of an ammonium interference up to a concentration of 200 mg/L NH4-N, which is unique in the market.
The use of the additional ammonium compensation reagent (REF 918045) is therefore no longer necessary. Additional information on this topic will be part of our upcoming water news mailing.
Please note, that the test procedure has changed.
An update of the photometers is not required.
Please find the new product information within the following link.
Note: Please save your special methods and measurement data prior to the update. More information can be found in the customer information
For old photometers (PF-11 etc.) asking for blank guidance is available here.
