Bluelab pH 4.0 – Calibration solution for accurate and reliable pH measurements

Bluelab pH 4.0 Calibration Solution provides a defined reference point for maintaining the accuracy of your pH measuring equipment. This ready-to-use pH 4.0 buffer solution is designed for calibrating pH electrodes, helping you obtain dependable readings when checking irrigation water and nutrient solutions. Suitable for Bluelab pH meters and other compatible instruments, it is available in three convenient sizes.

The second reference point for two-point calibration

Regular calibration is essential for keeping your pH meter working accurately. For measurements in the acidic range, Bluelab recommends two-point calibration using two reference solutions. Start with Bluelab pH 7.0 Calibration Solution, then use the pH 4.0 solution as the second calibration point. This allows the instrument to adjust its readings against two known reference values.

Three sizes to suit your calibration routine

Bluelab pH 4.0 Calibration Solution comes in three different sizes. The 18 ml single-use sachet contains a ready-to-use portion for one calibration. The 250 ml bottle is suitable for routine maintenance, while the larger 500 ml bottle is a practical option for frequent calibration or maintaining several instruments.

Always use fresh, uncontaminated calibration solution. When using bottled solution, pour the required amount into a separate container and never return used liquid to the original bottle. This product is intended for instrument calibration, not for lowering the pH of nutrient solutions.

Routine calibration and proper probe care

Bluelab recommends calibrating pH probes before their first use, after cleaning, whenever readings appear unusual and approximately every 30 days. Clean the electrode before calibration and rinse it between reference solutions to prevent cross-contamination.

For additional maintenance, the Bluelab pH Cleaning and Calibration Set provides useful probe care accessories. If you need a suitable instrument for monitoring your nutrient solution, explore the range of pH meters.
