Drop tester for pool water alkalinity
DUKE A drop tester is designed for easy measurement of total pool water alkalinity. The correct alkalinity is important for pH stability and trouble-free pool water maintenance. One package provides approximately 100 tests; the actual number depends on the measured alkalinity.
Why is water alkalinity important?
Total alkalinity describes the ability of water to resist sudden pH changes. It acts as a natural water buffer. If alkalinity is too low, pH may fluctuate rapidly and significantly, making correct adjustment difficult. Proper alkalinity helps keep pH stable and makes overall pool water care easier.
What is the correct pool water alkalinity?
The optimal total pool water alkalinity is generally considered to be 80–120 mg/l (ppm). In this range, water is sufficiently stable and pH adjustment is usually easier.
If pH keeps fluctuating, measure alkalinity
A typical sign of low alkalinity is when you set the correct pH but it changes significantly again soon afterwards. Adding more pH PLUS or pH MINUS may not solve the problem. In this case, first measure the water alkalinity and adjust it if necessary.
Correct alkalinity makes pool maintenance easier
Stable alkalinity helps limit pH fluctuations, may reduce consumption of pH adjustment products, and creates suitable conditions for pool chemicals to work correctly. The tester can be used in pools treated with chlorine and chlorine-free chemicals.
Simple drop testing
DUKE A uses a conventional drop testing method requiring no electronic device, batteries or test strips. Test a pool water sample according to the included instructions. The result easily shows whether the water alkalinity is within the recommended range and needs adjustment.
