Hanna pH 7.0 Buffer Calibration Solution - 500ml - NIST Traceable

NIST-Traceable pH 7.01 Reference for Meter Calibration -- HI7007L

Hanna pH 7.01 Buffer Calibration Solution provides a precise, stable reference point for single- or two-point pH meter calibration. Traceable to NIST standards, this 500ml solution suits calibration across hydroponic systems, water quality testing, and general laboratory use. The air-tight, tamper-proof opaque bottle protects solution integrity for a five-year unopened shelf life, and the bottle is clearly labeled to prevent mix-ups with other calibration solutions.

Key Features & Benefits

• NIST-Traceable Calibration Standard: Each batch is traceable to NIST standards, supporting the accuracy of your pH calibration process.
• pH 7.01 Reference Accuracy: A stable, reliable calibration point for compatible Hanna pH meters.
• Clearly Labeled Bottle: Bottle printing and cap color help you identify the correct buffer at a glance and avoid mixing up calibration solutions.
• Air-Tight Tamper-Proof Opaque Bottle: Sealed construction protects the solution from light and contamination for maximum shelf stability.
• Five-Year Shelf Life (Unopened): A long shelf life reduces waste and supports bulk purchasing without concern over expiry.

Who Should Use This

Hydroponic growers, greenhouse operators, laboratory technicians, and water quality professionals who use Hanna pH meters and need accurate, documented pH 7.01 calibration solutions for routine meter maintenance.

Compatibility

Compatible with Hanna Instruments pH meters and probes requiring pH 7.01 calibration buffer. A temperature chart on the label shows actual pH values at various temperatures.

Frequently Asked Questions

Is this solution NIST traceable?

Yes -- each batch of this Hanna buffer solution is traceable to NIST standards. That traceability supports certified calibration accuracy for your pH meter.

How long is the shelf life of this solution?

Unopened bottles are formulated for a five-year shelf life. Once opened, use it within the timeframe indicated on the label.

Does this buffer contain dye for identification?

No -- Hanna's pH buffer solutions are formulated without added dye, since dye can stain the reference cell or junction of a pH electrode over repeated use. The bottle and cap are labeled clearly instead so you can identify the correct solution.

Why does the bottle include a temperature chart?

pH values shift slightly with temperature, so the chart on the label shows the expected pH value at different temperatures. This lets you calibrate accurately based on your solution's actual condition when it is not at room temperature.
