Suitable for HACH photometers
VISOCOLOR Powder Pillows for silica (HR and LR) are ready to use in HACH instruments. They do not require any further calibration, but instead use preprogrammed HACH methods and equipment.
Suitable HACH methods silica HR: 8185
Silicon is the second most abundant element in the earth's crust. By decomposition of natural rocks, silica is added to water. An adequate treatment of boiler feed water is necessary to avoid corrosion as well as sediment accumulation of the heating system, and thus maintain its durability and efficiency. However, a high content of silica can lead to acid-fixed deposits (so-called silicate stone) and thus restrict a safe, trouble-free operation. Targeted monitoring of silica concentration allows a more efficient operation and can prevent costly downtimes.
The test is delivered without color scale and can be evaluated only with a photometer.

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.

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.
