5-in-1 Aquarium Water Quality Tester, Backlit LCD Screen, Digital Temperature Meter, pH, EC, TDS

Features: 1. 5 in 1 Function: The EC PPM water tester can test pH, TDS, EC, salinity and temperature, making it a versatile tool for a range of applications including saltwater swimming pools, hot tubs, aquariums, drinking water, hydroponics and koi ponds. . It provides reliable and rapid measurements for various water quality parameters.2. User-Friendly and High Accuracy: This PH EC TDS temperature meter is easy to use and offers high accuracy in its measurements. It ensures that you can easily monitor and maintain optimal water quality in different environments, helping you keep your water bodies clean and healthy.3. Mode Switch Function: The included water quality tester allows for simple monitoring and maintenance of ideal salt levels in saltwater pools.It accurately measures salt content, ensuring efficient operation of your salt chlorinator.Ideal salt ranges are 2,700 to 3,400 ppm for swimming pools and 2,000 to 3,000 ppm for spas, with an easy mode-changing function.4.Automatic Temperature Compensation: The digital pH meter features three-point calibration (4.00, 6.86, 9.18) and automatic temperature compensation (ATC) from 32 to 122°F, ensuring consistent readings regardless of water temperature.The large, backlit LCD screen provides easy readability in all lighting conditions, making it a convenient tool for maintaining pool water quality.5. Phase test for swimming pools: the pH meter measures pH values ​​ranging from 0.00 to 14.00.For optimal performance and clean water quality, it is recommended to maintain a pH between 7.2 and 7.8, depending on the type of pool (fiberglass or tile).The meter also offers several salinity test modes, including general (0 to 9,999 ppm), seawater (10 to 200 ppt), and drinking water (0.01 to 25%), ensuring accurate and reliable results when switching to salinity mode.Specifications:Item Type: Water Quality TesterMaterial: ABSLength: approx.18 cm / 7.09 inchesBattery: 3 x 1.5V LR44 button cell batteries (not included)Temperature range: 0.0°C to 60°C (32.0°F to 140°F)TDS range: 0 to 10,000 ppmpH range: 0.00 to 14.00 pHEC range: 0-10,000 μs/cmTemperature resolution: 0.1°C, 0.1°FTDS resolution: 1 ppmpH resolution: 0.01 pHEC resolution: 1 μs/cmTemperature accuracy: ±0.5°CTDS accuracy: ±2% F.SpH accuracy: ±0.05 pHEC Accuracy: ±2% D.S.Weight: approx.155.00 g / 5.47 ozHow to use:How to calibrate the pH meter?1. Prepare three beakers, each containing 250 ml of pH 4.00, pH 6.86, and pH 9.18 standard solutions.2. Rinse the electrode with clean distilled water and dry it. Turn on the pH meter and set it to pH mode.3. Immerse the electrode in the pH 6.86 buffer solution, wait for the reading to stabilize, press and hold the CAL button for 5 seconds. The display will show CAL, and when pH 6.86 flashes 3 times, the pH 6.86 calibration is complete.4. Repeat the steps above to calibrate the pH to 4.00 or 9.18.Refer to the instruction manual for details. Package List: 1 x Water Quality Tester, 1 x Accessory, 1 x Manual
