Specification BatteriesIncluded : 1 Brand : Yewhick BulletPoint : 10 pcs Electrodes fit HITBOX CT-520 CT 520 Plasma Cutter BulletPoint1 : pH EC Meter Hydroponic for All Growers: Whether growing in the greenhouse, horticulture, hydroponics, or aquaculture, pH/EC testing must be taken seriously. This pH tester is an essential tool with a pH range of 0 to 14 and an EC range of 0 to 19.99ms/cm to meet all your needs. A grower's tool that makes it easy to test pH/EC/TDS/Salt/Temp values. BulletPoint2 : Hydroponic pH Tester: The Yewhick pH tester digital can help control the pH of hydroponic nutrient solution. Maintaining an appropriate pH level is essential for nutrient uptake by hydroponic plants. Generally, the ideal pH range is 5.5~6.5. Regular monitoring and adjustment of pH help ensure better plant growth. BulletPoint3 : EC Meter Hydroponics: The high-precision EC ppm water tester makes it easy to test the EC value of the aqueous solution thanks to the unique high-accuracy probe. Ideal for hydroponic crops, it can be used to check the pH of nutrient solution. Typically, the optimal EC range for hydroponic crops is between 500 and 2000 µS/cm. BulletPoint4 : pH TDS EC Meter for Water Hydroponics: With automatic three-point calibration of 4.00, 6.86,9.18 it is easy to calibrate; with automatic temperature compensation of 32.0-122.0℉, it avoids measurement inaccuracies caused by liquid temperature variations; with automatic shutdown, battery life is well preserved. Up to 1500 hours of continuous operation, powered by 3 LR44 batteries. BulletPoint5 : Wide Application: Use the Yewhick pH EC Tester to monitor nutrients in indoor garden water and soil and check pH and EC levels when mixing media; measure pH in swimming pools and spas; know the pH of the mash when making beer or wine; monitor aquarium water conditions and test pH and salinity of koi pond water; and measure pH and TDS of well water, alkaline tap water, and other beverages.
