Product Description
Ensure the absolute accuracy of your pH meters, pen testers, and industrial monitoring systems with this professional-grade pH 9.18 Calibration Buffer Powder. Specially formulated using high-purity Sodium Tetraborate (Borax), this powder packet is pre-measured to prepare exactly.
Because pH electrode readings naturally drift over time due to dirt, aging, and chemical contamination, periodic calibration is essential. Using a freshly prepared sodium tetraborate solution provides an incredibly stable alkaline reference point, allowing you to fine-tune your instrumentation for soil testing, hydroponics, laboratory work, and water treatment setups.
