Calibration Buffer Capsules (pH 11)


For recommended basic calibration of optical pH sensors. Each capsule results in 100mL calibration buffer solution (PU=10).

Additional Information

PyroScience pH buffer capsules at pH 2 (item PHCAL2) and pH 11 are recommended for calibration of optical pH sensors. One capsule will produce 100 mL of buffers solution. Always prepare fresh buffers for calibration as the buffer has no preservative and the pH will change over time due to microbial growth. Commonly used pH buffers used for pH electrodes (uncolored and colored) should not be used as they interfere with the pH sensor.
