Ocean Free Calibration Solution pH4 & pH7
Ph probes require periodic calibration to ensure users continue to obtain accurate pH measurements.
OF calibration solutions pH 4 & pH 7 are specifically made to allow users to calibrate their probes to the highest possible accuracy.
Calibration should be performed with at least two standard buffer solutions.
As pH 7 is essentially, a “zero point” calibration (similar to zeroing a scale or balance), calibration at pH7 followed by calibration at pH4 as the second point of reference will enable users to perform a more accurate two point calibration.
Direction of use:
Rinse probe in clean water and briefly shake dry
Switch the pH meter on
Fill provided measuring cap with OF pH 7 until it reaches the 20ml mark
Submerge the probe in the pH7 solution until touches the base of the measuring cap and do required calibration
Rinse probe again in clean water and briefly shake dry
Fill provided measuring cap with OF pH 4 until it reaches the 20ml mark
Submerge the probe in the pH 4 solution until it touches the base of measuring cap and do required calibration.
