Pool-I.D. – 3-in-1 Test Strips pH / Active Oxygen / Alkalinity TSL 200 50 pcs

With 50 strips per tub, the Pool-I.D. TSL 200 covers three of the most critical water parameters in a single dip — pH, Active Oxygen (O₂/MPS), and Total Alkalinity — making it the go-to choice for pools and spas treated with oxygen-based or MPS sanitisers. Each strip delivers a result in seconds via colour comparison, removing the need for liquid reagents or separate test kits. Vacuum-sealed foil packaging protects each strip from ambient moisture, preserving accuracy across the full 50-strip life of the tub.

What this strip measures

The TSL 200 targets the three parameters that matter most in active-oxygen-treated water. pH confirms whether the water is within the comfortable 7.2–7.6 range for bathers and equipment. The Active Oxygen (O₂/MPS) pad gives a fast read of your sanitiser level, ensuring effective disinfection without overdosing. The Alkalinity pad checks the buffering capacity of the water, which keeps pH stable between treatments and protects pool surfaces and heat exchangers from aggressive water.

Ease of use & testing frequency

Testing takes only a few seconds: dip the strip, withdraw it horizontally, wait the indicated time, and compare the three colour pads simultaneously to the reference chart on the label. Pool-I.D. recommends testing at least twice a week under normal bather loads, and three to four times weekly during periods of heavy use or hot weather. The compact tub is easy to store poolside or in a service kit bag, and the 50-strip count comfortably covers an entire season of routine checks.

Compatibility & application

These strips are specifically formulated for pools and spas using active oxygen (O₂) or MPS (potassium monopersulphate) as the primary sanitiser — a disinfection method increasingly popular as a chlorine-free alternative. They are not designed to measure free chlorine or bromine, so they pair naturally with an oxygen-based water-care programme. For mixed programmes or chlorine pools, Pool-I.D.’s broader TSL range offers alternative strip formats.
