Water Test Kits

The first step in configuring a water treatment system is to complete a full evaluation of your current water situation, conduct a needs analysis, and select the appropriate equipment to produce the results you require. There are several water conditions that need to be identified upfront for proper system selection, as well as incrementally during operation for water quality monitoring.


  • Water hardness is caused by high levels of calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers.


  • Iron can do great economic damage by staining laundry and porcelain fixtures and by producing an ‘off’ taste in beverages. In water supplies used for commercial beverage production, low levels of iron are critical.


  • The most widely used disinfectant for drinking water, chlorine is also important for cooling towers, other industrial equipment, and in the treatment of municipal wastewater. Its measurement and control are vital for both safety and economic reasons.

pH Levels:

  • In most natural waters pH ranges from 4 – 9, but are commonly kept above 7 because of carbonates and bicarbonates (alkalinity). The pH of water used in industry and boiler feed water is usually is kept within a narrow range.

SDI (Silt Density Index):

  • SDI testing is used to indicate the quantity of suspended solids and colloid material in feed water.
