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