Brief Introduction
Apera Instruments 201T-F pH/Temp. Electrode is featured with a proprietary lithium glass membrane for
fast and stable readings and a built-in temperature sensor for automatic temperature compensation. The
gel inner reference solution does not need to be refilled. This electrode is designed for testing in general
water solutions. The electrode may not work well in the following situations:
1.
Long-term testing in high temperature solutions (>122°F or 50°C)
2.
Frequent testing in strong alkaline (>12 pH) or acid (<2 pH) solutions
3.
Testing low ionic strength solutions like distilled or deionized water
4.
Testing caustic solutions that will corrode the polycarbonate housing of the electrode

How to Install the Electrode
1.
Find the BNC socket (where it shows pH ORP) on the pH meter; Open the rubber cap; Insert the
blue BNC connector of the electrode to the BNC socket while twisting clockwise until it's locked.
2.
Find the RCA socket (where it shows temp.) on the pH meter; Open the rubber cap; Insert the black
RCA connector of the electrode to the RCA socket directly.
3.
After installing the new electrode to your meter, a 3-point calibration must be performed to ensure
the accuracy.
How to Use the Electrode
1.
There is a proper amount of storage solution in the cap on top of the electrode. The pH glass
sensor tip is soaked in it to keep its sensitivity.
2.
Before measuring, loosen the bottle cap, then pull out the electrode while twisting
counterclockwise. Place the storage bottle at a safe position.
3.
Rinse the electrode with purified water and shake off excess water or blot-dry it with clean tissue
or filter paper. Never rub the glass membrane.
