Water-ID - PoolLab DPD No. 1 Reagent Tablets for Free Chlorine - Pack of 250 - TbsPD1250

Water-ID – DPD No. 1 Free Chlorine Reagent Tablets – Pack of 250

These genuine Water-ID DPD No. 1 tablets are photometer-grade reagents for accurately measuring free chlorine levels in swimming pools and spas. Each tablet reacts with the DPD indicator chemistry to produce a colour change that the PoolLab 1.0 photometer reads instantly, giving you a precise mg/l result — no guesswork, no colour-chart comparisons. A pack of 250 tablets means fewer reorders and uninterrupted testing for busy pool operators and service technicians.

De ce este important clorul liber

Free chlorine is the active disinfectant in pool water — present as hypochlorous acid, hypochlorite ion, or dissolved elemental chlorine — and it is the fraction immediately available to neutralise bacteria and other pathogens. Monitoring it regularly ensures your sanitiser dose is always effective: too little puts swimmers at risk; too much can cause irritation and equipment damage. The DPD No. 1 method covers a measurement range of 0.0–6.0 mg/l (ppm), spanning the full working range recommended for pools and spas.

Mod de utilizare

Fill the PoolLab 1.0 cuvette with your water sample, add one DPD No. 1 tablet, and gently agitate until it dissolves completely. Place the cuvette into the photometer and read the result immediately. Tablets are individually blister-packed in aluminium push-through blisters (10 per blister) to protect against moisture and contamination, preserving reagent integrity and shelf life throughout the pack.

Compatibilitate & depozitare

These tablets are formulated specifically for the Water-ID PoolLab 1.0 photometer. Always confirm your photometer model before ordering, as reagent calibration is device-specific. Store in a cool, dry location between 15–25 °C, away from direct sunlight and humidity, to maintain accuracy across the full 2-year tablet shelf life.
