? PH Meter, TDS&EC Meter is a professional instrument with multi-function, can be used to testing water ph?ph value is acid and base in numerical terms, and the unit is ph? and TDS (the weight of total dissolved solid of water,unit is mg/L or ppm). Conductivity (the ability of conduction current expressed in digit, unit is us/cm ) and the temperature.
? Easy to Use - 5 Seconds know water quality, Accuracy, Faster. Just remove the cap, immerse the PH or TDS meter in the solution, simply press “ON” button, then stabilized numbers will be showed on LCD screen in seconds. All make it be your FIRST water quality Test.
? High Accuracy - The numbers of the pH meter range from 0.00-14.00 (PH), while the numbers of the digital EC and TDS meters range from 0 to 19990 ppm. PH Resolution is 0.01pH, Accuracy ± 0.05pH.TDS: 0 ~ 9990ppm, Conductivity: 0 ~ 9990us / cm, Accuracy: ± 2%
? Auto-Off & Hold Function - Digital TDS meter and PH meter both have Auto-off function, it will automatically shut off after 5 minutes to save battery power. The TDS meter also design with lock function, making it easy to read and record. You can press the “HOLD” button or it will be automatic locked within 5 minutes.
? Wide Application - Suitable for several indoor and outdoor areas. Which can effectively ensure the quality and health of water. They are suitable for multiple occasions, such as drinking water, aquariums, hydroponics, spas, swimming pools and other water systems.
