5-in-1 Multifunctional Water Digital pH Meter：Measures pH (0.01 resolution), Temperature, EC, TDS, and Salinity simultaneously with lab-grade precision (±0.05pH/±2% TDS). Ideal for comprehensive safety checks on drinking water, aquariums, hydroponics, and beverages like coffee/juice. The auto-calibrated sensors eliminate manual errors, ensuring reliable results for health-conscious families and professionals.

Ultra-Precise 0.01pH Resolution & Advanced Stability：Features triple-electrode technology for ±0.05pH accuracy (industry-leading for home use) with 0-9999ppm TDS detection (±2% error margin). The temperature-compensated probe auto-adjusts to 0°C-60°C environments, preventing misreadings caused by hot/cold liquids. Critical for brewing perfect coffee, testing drinking water, or balancing aquarium ecosystems.

Smart Backlit Display & 5-Minute Auto-Hold Function：Large LCD with color-coded backlight (green=safe, red=alert) clearly shows all 5 parameters even in dim labs/underwater. The "HOLD" button freezes readings for 5 minutes while stirring – no more missed data! Waterproof IP67 rating survives accidental submersion, making it perfect for pool maintenance or rainy outdoor testing.

Effortless Operation for Daily & Professional Use: 3-step testing: Dip → Stir → Read! No complex setup –pre-calibrated out of the box. The ergonomic grip and sturdy electrode guard prevent damage during vigorous stirring. Includes °C/°F switchable temp readings (hold "TEMP" button) for global users.

Pre-Use Activation: Prior to first use or calibration, immerse the probe in water for two minutes to ensure proper activation, If the electrode is dry, please put the electrode into distilled water to keep it moist.
