201T-S pH/Temp. Electrode

User Manual

Brief Introduction

Apera Instruments 201T-S 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. It 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 erode the polycarbonate housing of the electrode

How to Install the Electrode

1. Find the 8-pin socket on the pH meter; Open the rubber cap; Insert the connector to the socket

with the notch correctly aligned. Twist on the metal ring to lock the connection.

2. 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.

4. Insert the electrode into your sample solution and stir it for a few seconds in the solution to remove

potential air bubbles, which may cause unstable readings. Then wait for the stable reading and

take the measurement.

5. After use, insert the electrode while twisting clockwise into the storage bottle, then tighten the

bottle cap. If the KCL storage solution (SKU: AI1107) in the cap is contaminated, please fill in new

storage solution (other brands’ storage solution may not work with this electrode).

How to Maintain the Electrode

1. Always rinse the glass bulb sensor on top of the electrode with purified water (distilled or

deionized water) before and after each test and calibration. For general contaminants stuck on

the glass bulb sensor, use warm soap water and a soft brush to clean off; For special

contaminants, please refer to the following table for proper cleaning solutions:

Contaminant

Cleaning Solutions

Inorganic metal oxide

Dilute acid less than 1mol/L

Organic lipid

Dilute detergent (weak alkaline)

Resin macromolecule

Dilute alcohol, acetone, ether

Proteinic haematocyte sediment

Acidic enzymatic solution (saccharated yeast tablets)

Paints

Dilute bleacher, peroxide

2. Make sure the glass bulb sensor is covered by the KCL storage solution (SKU: AI1107) in the

storage cap when not in use.

3. Never store pH electrodes in pure water like RO water, tap water, distilled water, or deionized

water as they will cause damage to the electrode.

4. Keep the electrode connector clean and dry. Use cotton balls with isopropyl alcohol to clean if it

gets dirty and then blow-dry it. This is to prevent a potential short circuit, which will undermine the

electrode’s performance.

5. pH electrodes do not last forever. They age through normal use and eventually will fail. The

regular service life of the pH electrode is 1-2 years. If you feel like the response of your pH

electrode is much slower, or the slope is lower than 90% (most Apera portable/benchtop pH

meters will show the slope data between every two points of calibration), it’s time to replace with

a new electrode to ensure accuracy.

Limited Warranty

We warrant this electrode to be free from defects in material and workmanship and agree to repair or

replace free of charge, at the option of APERA INSTRUMENTS, any malfunctioned or damaged

product attributable to responsibility of APERA INSTRUMENTS for a period of SIX MONTHS from the
