Alkalinity Test Kits

Alkalinity tests measure the levels of carbonate, bicarbonate, and hydroxide alkalinity. It is important to measure the amounts of phenolphthalein “P” alkalinity and total “T” alkalinity to evaluate the scaling potential, corrosivity, or both in water. These parameters are needed to calculate a Langelier or Ryzner index which determines the scaling and corrosion potential of water.

Our EndPoint ID alkalinity test kits feature the standard water testing chemistry of sulfuric or hydrochloric acid, phenolphthalein, and total alkalinity indicator. We also manufacture CHEMetrics Titrets which use a reverse-titration to measure total alkalinity. We also offer specialized kits for hydroxide (OH) alkalinity, burette tests and the Hach digital titrators.

There are three types of alkalinity: hydroxide (OH), carbonate (CO₃) and bicarbonate (HCO₃).

A key component of water treatment is the prevention of scale forming on heat transfer surfaces. Scale formation is the biggest problem caused by alkalinity and hardness ions. The hydroxide (OH) and carbonate (CO₃) ions will react with calcium and magnesium to form calcium carbonate and magnesium hydroxide scales.

Hydroxide (OH) alkalinity is critical in boiler water for corrosion control and managing scale formation. It can be measured by the calculation 2P-M = OH or directly by adding barium chloride (BaCl) to the sample and titrating to the phenolphthalein endpoint. We offer kits for both methods.

Carbonate and bicarbonate alkalinity are present in all natural waters. Total alkalinity indicator is used to measure the concentration of these anions by titrating with an acid. We offer alkalinity test kits tailored to your specific application.

Every application/system will have differing recommended alkalinity control ranges based on the water quality and how many cycles of concentration are in operation. When selecting your alkalinity test, it’s important to understand your application and test ranges. Give us a call with your requirements and we will recommend the kit best suited for your application.

Industrial workers may need to know how to test for alkalinity for multiple applications, including:

• Drinking water: Test kits can be used to evaluate the alkalinity of drinking water and check that it is safe for consumption.
• Boiler Systems: Boilers operate with specific control ranges for alkalinity to prevent corrosion within heating and steam generation processes and to prevent scale deposition.
• Cooling Towers: Monitoring alkalinity is a key factor in preventing scale formation and controlling corrosion based on the Langelier or Ryznar index.
• Wastewater: Various wastewater treatment processes require accurate measurement of the water’s alkalinity.
• Aquaculture: Alkalinity may be a key metric to test regularly when managing conditions in aquaculture.
• Pools: Pools need to maintain the proper alkalinity to stay safe for swimmers, and test kits can be a valuable tool for measurement.
• Soil irrigation: Water alkalinity tests may be necessary to create the right conditions for soil irrigation.
