We know that clear, safe water testing relies on more than just meters and instruments – the right reagents are equally important. That’s why we stock a
range of high-quality tablets designed for reliable and accurate results. Here’s a quick look at our most popular options and what they’re used for.
DPD No. 1 – Free Chlorine
Free chlorine is the active form of chlorine responsible for disinfecting water. DPD No. 1 tablets provide a simple and effective way to measure free chlorine levels in pools, spas, and drinking water systems. Regular testing ensures water is safe for swimmers and complies with regulatory standards.
DPD No. 3 – Total Chlorine
While free chlorine shows immediate sanitising power, total chlorine testing gives the complete picture by measuring both free chlorine and combined chlorine (chloramines). By using DPD No. 3 tablets alongside DPD No. 1, operators can easily calculate chloramine levels – a vital step for maintaining healthy, odour-free water.
Phenol Red Tablets – pH Testing
pH balance is crucial for water quality. If pH is too low, water becomes acidic and corrosive; if too high, it can reduce chlorine’s effectiveness and cause scaling. Phenol Red tablets are the go-to reagent for pH measurement, delivering quick and accurate results to keep water balanced and safe.
Alka-M Tablets – Total Alkalinity
Total alkalinity acts as a buffer, helping stabilise pH levels and preventing sudden fluctuations. Alka-M tablets make it easy to monitor and adjust alkalinity in pools, spas, and industrial water systems. Proper alkalinity levels also protect equipment and improve the efficiency of sanitising agents.
CYA – Cyanuric Acid
Often called a stabiliser or conditioner, cyanuric acid protects chlorine from rapid breakdown under UV sunlight. Testing CYA levels with our tablets ensures that chlorine remains effective without over-stabilising the water, which can make sanitation less efficient.
