FAQs
Q: Why do I need a pH 4 buffer solution?
A: pH 4 buffer is used to calibrate pH meters and pens. Since it has a fixed, known pH, your device should read exactly 4.00 — if not, it needs recalibration.
Q: How often should I calibrate my pH meter with this buffer?
A: Weekly for heavy use or professional setups, and monthly for hobby use. It’s also recommended whenever accuracy is critical, like before mixing nutrient solutions.
Q: Is this solution suitable for hydroponic nutrient testing?
A: Yes — it's specifically formulated to help calibrate pH meters used in hydroponic systems, where pH precision is essential.
Q: How do I use the buffer safely and correctly?
A: Pour a small amount into a clean container, immerse the meter probe, calibrate according to your device's instructions, then discard the used solution.
