This 3-in-1 water quality monitor is a professional tool designed for testing pH, temperature, and electrical conductivity (EC) levels in various solutions. It is suitable for use in aquariums, pools, hydroponic systems, soil-free growing environments, laboratories, and environmental water testing. Features: - Measures pH, temperature, and EC (electrical conductivity) in liquids - Utilizes imported IC components for high performance; replaceable electrode probe - Switchable temperature units (°C/°F) with long-term online monitoring capability - Easy EC calibration using a mini-screwdriver; automatic temperature compensation - Dual-range EC measurement available in both ms/cm (wide range) and µs/cm (narrow range) - Integrated chip enables automatic recognition of pH calibration solutions for simplified calibration - Clear LCD display with backlight shows all three readings simultaneously - Simple operation with instant result display - Ideal for use in water sources, hydroponics, aquariums, laboratories, spas, swimming pools, and other water systems - Certified by CE, FCC, and RoHS for safe, environmentally friendly, and accurate measurements Specifications: - Color: Blue - Material: ABS - Model: pH/EC-2981 - Plug Type: EU or US (optional) - EC Units: ms/cm, µs/cm (switchable) - Input Voltage: 230–240V (EU) / 110–120V (US) - Measurement Range: - pH: 0.00–14.00 - Temperature: 0–50°C (32–122°F) - EC: 0.00–19.99 ms/cm (0–2000 µs/cm) - Resolution: - pH: 0.01 pH - Temperature: 0.1°C (0.2°F) - EC: 0.01 ms/cm (1 µs/cm) - Accuracy: - pH: ±0.1 pH - Temperature: ±1°C (±2°F) - EC: ±2% F.S. - Temperature Compensation Range: 0–50°C (32–122°F) - Working Temperature: 0–50°C (32–122°F) - Power Supply: DC 6V - Device Size: Approx. 130 x 76 x 26mm (5.1 x 3.0 x 1.0in), excluding probe - Device Weight: Approx. 138g (4.9oz), meter only - Package Dimensions: Approx. 25 x 18 x 7cm (9.8 x 7.1 x 2.8in) - Package Weight: Approx. 487g (17.2oz) Package Contents: - 1 x 3-in-1 Water Quality Monitor with EC Electrode - 1 x User Manual - 1 x pH Electrode - 1 x Temperature Electrode - 1 x AC-DC Adapter - 2 x Suction Cups - 1 x Bracket - 1 x Mini Screwdriver
