Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : GIDIGI BulletPoint1 : 【Automatic Temperature Compensation】The GIDIGI pH meter with pH function to ensure that the pH value of the nutrient solution is maintained within the ideal range for hydroponic crops, promoting vigorous growth and nutrient absorption of crops. Different plants have specific pH preferences, and most nutrient solutions generally have a pH between 5.5 and 6.5. The pH ec tester with TEMP function protects sensitive crops and monitors temperature changes to prevent damage and optimize growth. BulletPoint2 : 【Hydroponic pH and ppm Meter】pH/EC meter works with EC meter to maintain precise nutrient levels to maximize crop yield and quality in hydroponic system. With pH ppm meter, you can easily measure pH and ppm when growing in DWC hydroponics, helping to maintain hydroponic acid-base nutrient balance, monitoring EC level allows you to adjust nutrient solution in time to ensure optimal plant growth. This is essential for hydroponic growers. BulletPoint3 : 【Multi Purpose pH Tester: pH meter tds】This hydroponic tester can measure the range of pH (0.01-14.00), EC (conductivity), TDS (0-9990ppm), temperature (32.0-122.0℉, 0.0-50.0℃), four-in-one, the newly upgraded probe resolution reaches 0.01, not only can test hydroponics, but also aquarium and fish tank water, drinking water, swimming pool, tap water, hot tub, brewing and other scenes. Easily meet your multi-scenario testing needs, allowing you to test anytime, anywhere. BulletPoint4 : 【pH EC Meter Readings are Stable and Reliable】This multifunctional water pH meter has automatic temperature compensation (32 to 122 ℉) to keep readings consistent. In addition to accurate and fast readings, the hydroponic water quality tester also provides an easy-to-read green backlit display, fast readings in low light or dim environments, and automatic shut-off: after five minutes of non-use. BulletPoint5 : 【Excellent After-Sale Service】 This 4 in 1 pH tester is your good helper, can help you grow vegetables and monitor your fish better.
