Buffer Solution delivers laboratory-grade calibration accuracy for water quality testing instruments. Formulated with mold inhibitors and traceable to NIST certified pH references, this buffer maintains ±0.01 pH unit precision at 25°C for reliable instrument standardization. WHY IT MATTERS Precision Calibration for Accurate Water Testing pH meters drift over time and require regular calibration against known reference standards. The Myron L pH 4 Buffer Solution provides the acidic endpoint for two-point or three-point calibration protocols, ensuring your water quality measurements remain accurate and trustworthy. NIST traceability means every bottle connects to national measurement standards, while the mold-inhibited formula extends shelf life and prevents contamination. Color-coded packaging eliminates mix-ups when working with multiple buffer values in busy testing environments. SPECIFICATIONS Technical Details pH Value 4.00 Accuracy ±0.01 pH units @ 25°C Traceability NIST Certified References Formulation Mold Inhibited Identification Color Coded COMPATIBILITY Works With Your Equipment This pH 4 buffer solution is compatible with all Myron L pH meters and probes, as well as most standard pH testing equipment requiring acidic reference calibration. Use alongside pH 7 and pH 10 buffers for complete three-point calibration across the measurement range. Ideal for reverse osmosis system monitoring, aquaculture testing, laboratory analysis, and industrial water quality control applications.
