About This

• 【10 in 1 Multifunction Water Quality Tester】This tester integrates TDS, EC, pH, S.G, Salinity (SALT), ORP, Hydrogen, Resistivity (MΩ), Fertility, and Temperature into one compact device. The green backlit LCD large screen allows clear readings even in low light. Widely used for swimming pools, aquariums, fish tanks, hydroponics, drinking water, spas, aquaculture, wine/beer brewing, coffee, and more (Batteries NOT Included)
• 【pH, ORP & Hydrogen Measurement】Precisely measure pH, ORP, and dissolved hydrogen levels in your water. pH range: 0–14.00 pH with ±0.05 pH accuracy. ORP range: ±999 mV with ±2 mV accuracy. H₂ range: 0–2400 ppb / 0–2.400 ppm with ±10 ppb / ±0.01 ppm accuracy. Ideal for monitoring water quality in pools, spas, and various water applications
• 【pH, Salinity, S.G & Resistivity (MΩ) Meter】Ideal for saltwater pools and marine applications — measure pH, salinity, S.G, and resistivity. Salinity range: 0–9999 ppm / 10–200 ppt with ±2% F.S accuracy. Salinity %: 0.01%–25%. S.G range: 0–1.222 for additional water density reference. MΩ range: 5 Ω–20 MΩ for water purity assessment. The high-precision salinity sensor ensures accurate monitoring for aquaculture and marine use
• 【pH, EC, TDS & Fertility for Hydroponics】Essential for hydroponic growers — measure pH, EC, TDS, and nutrient fertility levels of solutions. Ideal pH: 5.5–6.5, EC: 0.3–3.0 mS/cm. EC range: 0–9999 µs/cm / 10–400 mS/cm; TDS range: 0–9999 ppm / 10–200 ppt. Fertility range: 0–3 for nutrient concentration reference. Supports mS and PPM 500 unit switching. Ensures your plants absorb nutrients effectively
• 【High-Precision Sensor & Portable Design】Equipped with a high-sensitivity electrode and built-in auto temperature compensation (0–60°C / 32–140°F) for accurate readings in various environments. Green backlit LCD with auto sleep after 5 minutes of inactivity. Compact size: 1.65 × 1.65 × 7.44 inches, weight: 0.24 lb — replaces multiple single-function testers. One-key mode switching and reading hold function make field testing effortless. Includes 3 calibration powder packs for long-term accuracy (Requires 4× batteries, NOT included)
