Essentials Lab Buffer 4

Essentials LAB Buffer 4 is a precision calibration solution with a fixed pH of 4.0, used to calibrate pH meters and pens for accurate nutrient monitoring. This acidic buffer is essential for calibrating equipment that needs dual-point accuracy (e.g., pH 7.0 and pH 4.0), especially when working in environments where acidic nutrient solutions or runoff are common.

Made to laboratory-grade standards, Buffer 4 ensures your pH meter provides accurate, reliable readings, which is crucial for maintaining correct nutrient uptake and preventing pH-related plant issues in hydroponic, coco, or soil systems.

Key Features:

• pH 4.0 solution – for low-range pH calibration

• Ensures meter accuracy in acidic environments

• Designed for dual-point calibration with Buffer 7

• Suitable for all brands of pH meters and pens

• Long shelf life and lab-grade consistency

• Essential for growers using hydroponic, soil, or coco systems

• Available in various bottle sizes

How to Use:

1. Rinse the pH probe with distilled water.

2. Submerge probe in Buffer 4 solution.

3. Adjust meter until it reads 4.0.

4. For highest accuracy, calibrate with Buffer 7 first, then Buffer 4.

5. Clean and recalibrate regularly for consistent readings.
