Water Analysis Report
Evaluate the effect Scale Manager has on hard water, installed in a domestic situation. Test duration 60 days.
As per Waltham Electronics instructions.
A four bedroom two story residence circa 1920. Situated in Freeby Leicestershire.
Hardness is due to the presence of salts – Magnesium and Calcium. It is expressed as the equivalent of Calcium Carbonate (CaCo3). The Total Hardness is the sum of the Carbonate Hardness and Non-carbonate Hardness, depending on whether or not the Calcium or the Magnesium is combined with one of the stronger acids to form a sulphate or a chloride. The Carbonate Hardness can largely be deposited by boiling water and so driving off the loosely combined Calcium Dioxide (CaO2). For this Carbonate Hardness accounts for at least 90% of the deposits found in domestic plumbing. Non-carbonate Hardness, precipitating by concentration, can be a major source of problems in steam-raising situations.
Indicates the presence of suspended matter in water,and is measured by visual or photometric comparison of a sample with a suspension of colloidal silica. It is expressed as parts per million of silica. Suspended matter is measured directly by a gravimetric technique. It does not correspond with turbidity measurement that is
affected by the particle size of the matter present.
% Salts in suspension
Percentage of hardness salts ineffective.
Measure of Acidity and Alkalinity
Measure of water hardness.

Evaluation of Waltham Electronics, Scale Manger 2, commenced October 14 1996.
|Water Condition||Before test||1 hour||1 day||5 Days||15 Days||30 Days||60 Days|
|% Salts in suspension||0||49||87||98||92||93||91*|
*Turbidity and Percentage of salts in suspension will decrease as limescale deposits diminish
The results testify Scale Manager will reduce limescale by at least 90%, and would be 100% effective on Calcium
