Check2O Pool/Spa Test 6 in 1, 50 strips (Alkalinity, pH, Cyanuric Acid, Hardness, Free & Total Chlorine)

Check₂O Pool/Spa Test 6 in 1, 50 strips (Alkalinity, pH, Cyanuric Acid, Hardness, Free & Total Chlorine)

Check₂O 6 in 1 test strips provide fast, reliable testing for pool and spa maintenance. Each strip measures six essential parameters to help you balance water chemistry, protect equipment, and keep swimmers comfortable.

Convenient Form Factor

Dip-and-read operation with clear colour blocks for quick comparison. Each moisture-resistant tube contains 50 strips for routine testing.

Measurement Parameters and Graduations

Alkalinity (as CO₃²⁻): 0 – 40 – 80 – 120 – 180 – 240 mg/L

pH: 6.4 – 6.8 – 7.2 – 7.5 – 7.8 – 8.4

Cyanuric Acid (CA): 0 – 50 – 100 – 150 – 300 mg/L

Free Chlorine (as OCl⁻): 0 – 1 – 2 – 3 – 5 – 10 mg/L

Total Chlorine / Total Bromine: 0 – 1 (2) – 2 (4) – 3 (6) – 5 (10) – 10 (20) mg/L Total OCl⁻ (Total Br₂)

Total Hardness (as CaCO₃): 0 – 100 – 250 – 500 – 1000 mg/L

Reliable and Easy to Use

Clear, stable colour changes for straightforward interpretation. Regular testing helps prevent scaling/corrosion, eye/skin irritation, and ineffective sanitiser levels.
