Aquamaster pH 7.00 Calibration Solution | 100ml | NIST Traceable

🔬 Hit Neutral. Stay Accurate.

pH 7.00 is the neutral midpoint — and the most important calibration reference for any pH meter. The Aquamaster pH 7.00 Calibration Solution is a NIST-traceable, lab-grade buffer that locks in your meter's accuracy at the centre of the scale, giving you reliable readings across the full pH range.

Pair it with the pH 4.01 solution for a full 2-point calibration — the gold standard for precision growing. 🌱

✅ Why Use Aquamaster pH 7.00 Solution?

• 📐 NIST-traceable accuracy — meets international measurement standards
• 🧪 pH 7.00 reference point — the essential neutral midpoint for 2-point calibration
• 💧 100ml bottle — enough for multiple calibration sessions
• 🔒 Stable formula — store between 15–25°C for long shelf life
• ✔️ Compatible with Aquamaster meters and most pH meters on the market

📋 Usage Instructions

Pour a small amount into a clean cup, insert your pH probe, and calibrate per your meter's instructions. Close the bottle immediately after use and do not return used solution to the bottle. Store between 15–25°C.

💡 Pro Tip: Use pH 7.00 alongside pH 4.01 for a 2-point calibration — this gives you the most accurate readings across the full growing pH range (5.5–6.5).
