pH Calibration and Buffer Solution Kit
These buffer solutions have been standardized against N.I.S.T.-certified reference samples and are formulated to provide precise pH determinations. They are ideal for calibrating your pH meter. The buffers are color-coded to avoid error and accurate to within ±0.02 pH at 25°C (77°F). Each buffer contains a preservative/mold inhibitor. Temperature compensation charts are included with each buffer solution.
Our pH calibration buffer solution kit is sold in 1 ounce, 2 ounce, and 4 ounce sizes. Each kit contains one bottle each of pH 4.01, pH 7.0 and pH 10.01 solutions.
