Soak the sensing tip in either buffer 4, buffer 7, KCL solution or tap water for at least 30 minutes. Make sure that the sensing tip is immersed up to at least one inch from the tip. This procedure should be followed when unit is received or if the electrode is allowed to dry out. If unit is properly stored, this procedure is not necessary.

CALIBRATION OF THE PHH-1X

After conditioning, the

pen must be calibrated in a buffer solution close to the value of the sample to be measured. Calibration is performed by turning the CALIBRATION TRIMMER on the reverse side of the tester. The

Litmustik@ designed for single point calibration only. For accurate measurements, periodic recalibration is recommended.
