**5-in-1 pH Meter:** This compact device measures pH, TDS (Total Dissolved Solids), EC (Electrical Conduction), salinity, and temperature. Thanks to its smart chip, it provides fast and stable measurements and features automatic temperature compensation. The intuitive interface allows you to switch modes with a single click, eliminating the need to change probes.**Backlit LED Display:** Featuring a high-contrast display, data is clearly readable even at night or in direct sunlight, avoiding annoying glare. Measurements can be obtained without ambient light, whether outdoors or in dark environments. Simplified two-point calibration ensures accuracy and durability. Ideal for aquariums, hydroponic systems, swimming pools, and hobby labs.**High Precision (0.01 pH):** This pH meter uses a high-quality glass electrode and intelligent algorithms to guarantee an accuracy of ±0.01 pH, detecting even minute changes in pH. Whether used for scientific research, aquaculture, drinking water analysis, or pool water quality control, it provides reliable, lab-grade data, giving you peace of mind with every measurement.[Rugged and Durable Design]: This pH meter features a high-strength ABS housing with an anti-corrosion coating, making it compatible with a wide range of corrosive solutions (acids, alkalis, etc.) with pH values ​​from 0 to 14. The wear-resistant glass electrode is suitable for harsh environments (chemical, electrolytic, and battery applications). The protective cap maintains sensor sensitivity and prevents wear and contamination between uses.[Fast Response]: Thanks to innovative sensor technology, waiting time is significantly reduced. The pH meter stabilizes and takes only 30 seconds to measure after immersion in a solution, completing the measurement in less than a minute, ensuring efficient operation even in frequent measurements or emergency situations.
