Description
The Vivosun 18-Pack pH Meter Buffer Solution Powder (pH 6.86 / 4.00 / 9.18) is a precision calibration kit designed to maintain the accuracy and reliability of digital pH meters. It provides essential reference solutions for ensuring consistent and trustworthy pH readings across hydroponic, soil, and laboratory applications.
Each individually sealed packet contains pre-measured buffer powder that dissolves quickly in distilled or deionized water, allowing fast and accurate calibration without guesswork. With high stability and ±0.01 pH accuracy at 25°C, these buffer solutions ensure long-term reliability for testing equipment. The three standard calibration points (4.00, 6.86, and 9.18) make it suitable for a wide range of measurement needs, while the portable packaging allows convenient use in the field or grow setup.
