Description This new 3-in-1 water quality monitor is professional and necessary tool for testing pH / Temperature / EC of the solution level. Suitable for aquarium pool, soil-free growing, laboratory, and environment water.Features:Widely used to measure the pH / Temperature / EC (Electric Conductivity) of solution water.Imported IC and high cost performance, the electrode probe can be replaced.Test temperature in / (switchable unit) and can online monitoring for a long time.Easy calibration of EC with just a mini-screwdriver and automatic temperature compensation.Test the EC with both wide range(ms/cm) and narrow range(us/cm) at will.Chip pH can automatically identify calibration fluid for pH automatic calibration function.Clear LCD with backlight, 3 results displayed simultaneously. Easy to use and provide instant display of results.Apply in water sources, soil-free growing, aquarium, hydroponics, laboratory, spas, swimming pools and other water systems.CE, FCC RoHS certificated to offer safer, more environmentally friendly and preciser measurement.Specifications:Color: BlueMaterial: ABSType: pH/EC-2981Plug Type: EU / US (Optional)EC Unit: ms/cm, us/cm (Switchable)Input Voltage: 230240V (EU) / 110120V (US)Range: pH: 0.00 14.00pH Temperature: 0 50 (32 122) EC: 0.00 19.99ms/cm (0 2000us/cm)Resolution: pH: 0.01pH Temperature:0.1(0.2) EC: 0.01ms/cm (1us/cm)Accuracy: pH: 0.1pH Temperature: 1(2) EC: 2%F.STemperature Compensation: 0 50 (32 122)Working Temperature: 0 50 (32 122)Power Supply: DC 6VItem Size: Approx. 130 * 76 * 26mm / 5.1 * 3.0 * 1.0in (Excluding EC Probe)Item Weight: Approx. 138g / 4.9oz (3 in 1 Meter Body)Package Size: Approx. 25 * 18 * 7cm / 9.8 * 7.1 * 2.8inPackage Weight: Approx. 487g / 17.2ozPackage List:1 * 3 in 1 Water Quality Monitor with EC Electrode1 * User Manual1 * pH Electrode1 * Temperature Electrode1 * AC-DC Adapter2 * Suction Cups1 * Bracket1 * Mini Screwdriver
