5.1.2 Connect the power adapter
Plug the power adapter tightly into the DC9V socket. The power’s voltage should meet the
requirements listed on the power adapter.
5.1.3 Things needed in addition to what’s included in the box
A clean cup, distilled water (8-16oz), and tissue papers for rinsing and drying the probe.
5.2 pH Electrode Information
5.2.1 pH Electrode
The meter comes with the 201T-F 3-in-1 combination electrode with a built-in temperature
sensor, which enables the automatic temperature compensation. This electrode is only
suitable for regular water solutions’ pH testing. Please refer to Section 9 for ideal pH
electrodes to use for other specific applications. The electrode’s housing adopts
polycarbonate materials, which is resistant to shocks and corrosion. A 3M KCL storage bottle
comes with the electrode, which is for storing the electrode when not in use to keep the
sensitivity of the probe.
5.2.2 Technical Specifications of the 201T-F pH Electrode
Measurement Range: 0 - 14 pH, 0 - 80˚C (32 – 176˚F)
Junction: Single Ceramic
Reference Electrode: Ag/AgCl
Connector: BNC
Size: ø12*160 mm
Temperature unit: 30K Thermistor
5.2.3 Electrode Connectors
The pH electrode has two connectors: the BNC connector connects the pH probe; the RCA
connector connects the temperature sensor. Plug these two connectors into ‘pH/mV” and
“TEMP” sockets. Please note not to pull the cables in case of poor contact. Please keep the
connectors clean and dry. Refer to section 4.7 regarding how to properly maintain the pH
electrode.
5.2.4 Use the Electrode
Screw off the KCL storage bottle, and put it aside (do not dump or spill the KCL solution).
Prepare a cup of distilled water, and rinse the electrode in it for a few seconds. Gently shake
the probe to remove excess water, and dry it with clean tissue paper (DO NOT rub or wipe
the probe, just use paper to dap off excess water). Gently stir the electrode for a few seconds
