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.
