4-in-1 pH Meter, Water Quality Tester for pH/TDS/EC/Temperature, IP67 Digital pH Meter with Auto Calibration and Backlit LCD for Hydroponics, Garden, Pool, Aquarium

4-IN-1 PH METER: The water quality tester can simultaneously measure pH, TDS (ppm), EC (conductivity), and temperature with high accuracy. You can use it to test water hardness, pH, or liquid conductivity. Note: EC and TDS modes are stable for a long time. EC/TDS/pH modes can be quickly reset to the factory calibration state, eliminating the need for frequent calibration.

HIGH ACCURACY: The 4-in-1 pH tester is equipped with a highly sensitive glass electrode combined with a fully intelligent chip. The measurement range is 0.00-14.00 pH, and the measurement accuracy reaches 0.01 pH, providing fast, accurate, and stable measurement results.

AUTOMATIC CALIBRATION: You no longer have to worry about calibration. Simply immerse the electrode in a pH standard solution and press the MODE/CAL button for 3 seconds. The LCD display will then flash 3 times, indicating automatic calibration. The tester comes with 3 sachets of calibration powder (standard: pH 4.00, pH 6.86, pH 9.18).

AUTOMATIC TEMPERATURE COMPENSATION: Temperature can affect the pH value of a solution. The electronic pH meter supports automatic temperature compensation, which can correct the pH value within the temperature range of 0°C to 60°C (32°F to 140°F), allowing you to obtain accurate and stable readings under all conditions.

EASY-TO-READ BACKLIT LCD: The hydroponic pH meter features a digital LCD display and a large backlit screen, so you can view data clearly even in a dark environment.

WIDE USE: Thanks to the IP67 waterproof and dustproof design, the pH meter is suitable for kitchens, hydroponic rooms, laboratories, outdoors and other humid environments. Measure pH/TDS/EC/temperature values of drinking water, tap water, swimming pools, aquariums, bathtubs, spas, wine, beer, SPAs, aquaculture, aquariums and other liquids anywhere, anytime.
