The PHC281 series probe is a pH refillable probe made for difficult samples with a built-in
temperature sensor
(Figure
1 or 3 m (3.28 or 9.84 ft) cable and is intended for laboratory use. The pH refillable probe
has a high electrolyte flow rate and a large open junction ideal for difficult samples, such
as Low Ionic Strength (LIS), Ultrapure, dirty samples and samples with high solids
content. The probe is not suitable for use with organic solvents. A 59-mL bottle of 2.44 M
KCl Electrode Filling Solution is included with the probe.

Page 3: Calibration Procedure
Calibration Before calibration: The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached. It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is configured to use the same calibration options. -

Change measurement options Methods are groups of default or user-defined settings relevant to specific applications. If the meter is set to the default method and the Modify Current Settings option is chosen, a prompt for a new name is shown after the changes are entered. The settings are saved with this name to distinguish them from the default method settings, which cannot be changed. - Page 8 4.
