Product Description

The Bluelab pH 7.0 Calibration Solution is a neutral pH buffer liquid used to calibrate pH measurement tools such as pH pens, meters, probes, and controllers. Calibration solutions ensure that your pH device reads accurately at the neutral point of the scale (pH 7.0), which is especially important in gardening, hydroponics, laboratory testing, aquariums, and other applications where precise pH measurements matter. After calibrating with pH 7.0, most instruments are then calibrated with a second buffer (e.g., pH 4.0) to complete a full two-point calibration process.

Key Features

• Neutral Reference Standard: Serves as the baseline calibration point (pH 7.0) for pH testers.
• Ensures Accuracy: Regular calibration helps maintain reliable measurement results.
• Large 500 ml Size: Enough volume for repeated calibration cycles before needing to restock.
• Protects Equipment: Using correct calibration solutions can help prolong the life and performance of pH probes.

Typical Use

1. Pour a small amount of solution into a clean container (do not calibrate directly in the bottle).
2. Rinse your pH probe or meter with clean water and immerse it in the calibration solution.
3. Follow your meter’s calibration procedure until it confirms the neutral pH point.
4. After this, you would normally calibrate with a second buffer (e.g., pH 4.0) for full two-point calibration.
5. Rinse the probe thoroughly after calibration.
