Chlorine and pH Test Kits for Pool Maintenance

TK-1 professional pool test kit from Waterstar Egypt: OTO liquid for chlorine and Phenol liquid for pH, for daily service crews and personal use alike.

You Cannot Manage What You Do Not Measure

After thirty years around pools I can smell trouble in a plant room, but even I never guess at water chemistry, because the two numbers that decide bather safety are invisible. Free chlorine must sit between 1 and 3 ppm to sanitize without irritating, and pH must hold between 7.2 and 7.6 for that chlorine to work at full strength. Water can look perfect a full day before it turns; the only early warning you get is the one you take yourself, at poolside, with drops and a colour scale. A test kit is the least expensive instrument on any pool, and the one that earns back its price the fastest.

Inside the TK-1

Our TK-1 is a professional test kit for chlorine and pH built for daily service work yet simple enough for personal use by any pool owner. It carries OTO liquid, which colours a water sample in proportion to its chlorine, and Phenol liquid, which shifts colour with pH; fill the two cells, add the drops, and read each result against the moulded colour standards in under a minute. There are no instruments to calibrate, no batteries to die in the sun, nothing to go out of order in a hot plant room. Cap the reagents tightly, store them in the shade, and replace them each season so the colours stay honest.

Build the Habit, Then Ask Us the Numbers

Test at the same hour every day, before the first bathers, and log both readings; a written trend reveals a slipping chlorinator or a drifting pH a week before the water shows it. Take the sample at elbow depth, away from the return jets, so you read the pool and not the pipework. The TK-1 comes from Waterstar's ISO 9001 factory in Badr City, Egypt, the same plant that builds our automatic chlorinators, and ships across thirteen MENA markets. If your readings keep wandering from the targets, send our factory engineers your pool volume and latest results; they will reply with a practical dosing recommendation at no cost.
