Why is my pH meter not working?
If the reference junction on the probe is not clean the probe may become unresponsive. Field Electrodes: Regularly soak the electrode in a 1:1 bleach water solution for 15-30 minutes to reduce the chances of a clogged reference junction. If hard deposits have built up on your probe (ie.
How can I calibrate my pH meter at home?
Pour some pH 4.0 calibration solution into a small cup and insert the electrode. Once the meter is calibrated with the 4.0 solution, it will flash 7.0. Rinse the probe with distilled water, dry it and insert it into a cup of 7.0 calibration solution. Once it stops flashing, it is calibrated and ready for use.
How do you calibrate an old pH meter?
Calibrating Your pH Meter. Place your electrode in the buffer with a pH value of 7 and begin reading. Press the “measure” or calibrate button to begin reading the pH once your electrode is placed in the buffer. Allow the pH reading to stabilize before letting it sit for approximately 1-2 minutes.
How do I know if my pH sensor is working?
pH Electrode Test Procedure
- Set the pH/mV switch on the pH meter to the mV position.
- Connect a shorting plug to the input on the pH meter, or connect a precision mV generator with a 0 mV input.
- Disconnect the shorting plug/precision mV generator, and connect the electrode that will be tested.

How to calibrate the Oakton ecotestr pH 2 Pocket pH meter?
How to Calibrate the Oakton EcoTestr pH 2 Pocket pH Meter. This brief video demonstrates Oakton pocket pH meter calibration. Calibration Steps. Start with a pH 7 buffer ; Remove the cap, turn on the meter, then press the “Cal” button; Place the ph meter into the buffer. Make sure the bulb is completely submerged. Wait for the meter to stabilize.
How do you calibrate a pH tester?
Rinse the cap after use. Calibration: This tester allows up to 3-point calibration. Start with pH 7.0 buffer • Press on/off button to power on. Immerse sensor in about 20 mm of buffer and stir gently. Wait for displayed value to stabilize at or near pH 7.0 • Press cal button to enter calibration sequence.
How do I read the pH value from the sensor?
sensor in at least 20 mm of test solution • Stir once and let the reading stabilize. Note the pH value • Press hold/ent button to hold (HO) the reading. Annunciator
