The PHC201 series probe is a non-refillable, semi-liquid gel-filled combination pH probe
with a built-in temperature sensor
comes with a 1 or 3 m (3.28 or 9.84 ft) cable and is intended for laboratory use. The probe
provides pH measurement in general aqueous applications. The probe is not suitable for
use with organic solvents, low ionic strength, wastewater, high solids or high alkaline sample
types.

Figure 1 Probe overview Probe soaker bottle Reference junction Standard probe (1 or 3 meter cable) Glass bulb and temperature sensor Soaker bottle holder Preparation for use To prepare the probe for initial use: 1. Turn the probe soaker bottle cap counter-clockwise to loosen the cap. Remove the soaker bottle from the probe. -
Page 3: Calibration Notes
Calibration notes • pH buffers can be used in any order. Use buffers that are two pH units apart. • Additional standard sets along with the minimum number of calibration points can be selected in the Calibration Options. For a two point calibration, it is recommended that two buffers be selected: one with a pH above and one with a pH below the expected sample pH. -
Page 4: Sample Measurement
Sample measurement Before measurement: The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached. If complete traceability is necessary, enter a sample ID and operator ID before measurement. Refer to the HQd meter manual for more information. -
Page 5: Run A Check Standard
Run a check standard The run check standard feature validates instrument performance between sample measurements. Use the run check standard feature for periodic or user-defined interval measurements of a traceable standard solution. Set the criteria for check standards from the PHC201 Settings menu. Note: Access control must be off or a valid password must be entered before any of the check standard method options can be changed. -
Page 6: Change Measurement 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 7 4.

2. Fill the probe storage cap or soaker bottle half full with Hach Electrode Storage Solution or 3 M potassium chloride (KCl) solution. 3. Put the soaker bottle on the probe and tighten the soaker bottle cap. 4. Make sure that the solution in the storage cap or soaker bottle completely covers the glass bulb and reference junction. - Page 11 Message or symptom Possible cause Action Calibration errors Calibration not done correctly Recalibrate using freshly prepared pH buffers.
