Why pH 4.0 Calibration MatterspH 4.0 represents the acidic endpoint commonly used in two-point calibration. Calibrating your pH meter at both pH 4.0 and pH 7.0 (or pH 10.0) ensures accuracy across the full measurement range. This is especially important for applications testing acidic solutions or requiring precision in the lower pH range.Two-Point CalibrationFor optimal accuracy, use pH 4.0 buffer with pH 7.0 buffer for standard two-point calibration. For even greater precision across the full pH range, perform three-point calibration using pH 4.0, pH 7.0, and pH 10.0 buffers.Package Contents20 individual packets × 20ml pH 4.0 buffer solution = 400ml totalCompatible with HM Digital PH-200, PH-80, COM-300, and other pH meters requiring pH 4.0 calibration.
