This Standard Reference Material (SRM®) is intended for use in preparing solutions for calibrating electrodes for pH measuring systems. NIST-188, potassium hydrogen tartrate (KHC4H4O6), is a material of high purity and uniformity. A solution saturated with potassium hydrogen tratrate at 25 ± 1 Grad Celsius is recommended as a standard for the calibration of pH equipment betweeen 25 and 95 Grad Celsius. The 0.01 molal solution is recommended as a standard for the range 0 to 60 Grad Celsius. /// Sample value(s) - please ask for current certificate.
