H1 Title: Bluelab pH 7.0 Calibration Solution (250ml / 500ml Bottle)

Short Description (Intro Paragraph): Ensure your pH readings are always perfectly accurate with Bluelab pH 7.0 Calibration Solution. This is the standard "buffer" solution, NIST-certified, and essential for calibrating all Bluelab pH measuring devices. Regular calibration extends your probe's life and delivers reliable data for hydroponics, aquariums, or lab work.

Why Calibrate with pH 7.0 Solution?

Over time, all pH measuring instruments (like pH pens and meters) will drift and lose accuracy. To ensure your meter is functioning correctly, you must clean and calibrate it at least once a month.

Bluelab's pH 7.0 solution is the first and most critical step in the calibration process. It acts as the neutral reference point (buffer), allowing the device to establish its baseline. After calibrating to pH 7.0, you then proceed to calibrate with pH 4.0 (slope) to complete the process.

Key Benefits of Bluelab pH 7.0 Solution

• NIST-Certified Accuracy: Manufactured to a high, traceable standard and certified by the National Institute of Standards and Technology (NIST).

• Perfect Compatibility: Essential for and recommended by Bluelab for all their pH products (including the Bluelab pH Pen, Combo Meter, and Guardian Monitor).

• Extends Probe Life: Using fresh, genuine calibration solutions helps maintain the sensitivity and prolong the functional life of your pH probe.

• Multiple Sizes: Available in 250ml and 500ml options to suit your frequency of use.

How to Use and Store (Crucial Information)

To ensure the solution remains accurate and to avoid contaminating your probe, please follow these rules strictly:

How to Use:

1. Never calibrate directly in the bottle. Always pour a small amount of solution into a clean, separate plastic cup.

2. Dip your cleaned probe into the pH 7.0 solution and follow your meter's calibration instructions.

3. Do Not Reuse: Never pour the used solution from the cup back into the main bottle. Discard the used sample after calibration is complete.

Storage:

• Store the bottle in a cool, dark place, away from direct sunlight (light can alter the solution's value).

• Always secure the cap tightly immediately after use.

• Keep out of reach of children.

Using Bluelab pH 7.0 solution is the professional way to guarantee you are providing your plants (or system) with the precise pH environment they need to thrive.
