Water Tester for pH and Active Oxygen (O₂)
The pH / O₂ Water Tester is a manual colour comparator designed for quick and convenient measurement of pH and active oxygen (O₂) levels in swimming pools and spa water. Regular water testing helps maintain proper water balance and ensures the effective performance of active oxygen water treatment products.
Key Features
- Manual colour comparator water tester.
- Measures pH and active oxygen (O₂) concentration.
- Quick and easy testing method.
- No batteries or power supply required.
- Suitable for swimming pools and spa pools.
- Reusable tester.
- Easy-to-read colour comparison scale.
When to use?
- Before the start of the swimming season.
- For regular water quality monitoring (recommended at least once a week).
- Before adjusting active oxygen or pH levels.
- After topping up the pool or spa with fresh water.
- After intensive pool or spa use.
- After heavy rainfall.
Instructions for use
- Remove the tester cap and rinse the tester with pool water.
- Fill both tester chambers with water up to the marked level. Collect the water sample approximately 0.5 m from the pool edge and 5–10 cm below the water surface.
- Place one pH reagent tablet into the pH test chamber.
- Place one active oxygen (O₂) reagent tablet into the active oxygen test chamber.
- Close the cap and gently shake the tester until the tablets have completely dissolved.
- Compare the water colour with the tester's colour scale to determine the pH and active oxygen values.
Measured Parameters
