- Practical safety: The digital water monitor provides quick, accurate readings of chlorine content and pH for pools and spas. Chlorine safe range: 1.2–1.7 ppm; pH safe range: 7.2–7.8. This helps keep water safe and convenient to manage. - Practical design: Hand-pen type with a compact case that fits in a bag for portable use. Automatic temperature compensation allows accurate pH readings across 0 °C to 80 °C (32 °F to 176 °F) without temperature adjustments. - Fast and precise: Delivers quick results without color charts or test strips. pH resolution 0.01 with accuracy ±0.05, covering the full 0–14 pH range. Safe measuring ranges: chlorine 1.2–1.7 ppm; pH 7.2–7.8. - Wide application: Suitable for swimming pools, tap water, home use, laboratory testing, aquarium maintenance, and more. An electrical tester for measuring pH and chlorine (Cl2) in water, used to regularly monitor the pH and chlorine content of pools, spas, and various water sources. - Use scenarios: Regular pool/spa maintenance to maintain safe chlorine and pH levels; home water testing for drinking or cooking water; aquarium upkeep to protect aquatic life and water quality.
