ATC function (Automatic Temperature Compensation) - temperature measurement and compensation indication of the tester in the range of 0-50°C. Thanks to this, we obtain an accurate result of acidity of a given liquid.

Due to the pH variability of the liquid relative to its temperature, only an acid meter with the ATC function allows to obtain a reliable result consistent with the actual average value.

The pH tester complies with EU directives and is marked with the CE mark. In addition, the pH tester is made of materials that meet the strict requirements of the EU ROHS directive.

Do not touch the sensor electrode, the oil on the skin can damage the sensor and affect the readings.

1. Make 3 solutions (4,01 pH; 6,86 pH, 9,18 pH) with known pH using 250 ml of distilled water each and calibration buffers.
2. Dip the tester electrode into a solution with pH 6,86 (at 25 ℃), gently stir and wait for the reading to stabilize (no changes for 5 seconds).
3. Press the "CAL" button (calibration) for 5 seconds and release. Wait for the display to show 6,86 pH and stop flashing.
4. Clean the electrode in distilled water and dry (e.g. using a paper towel), then immerse the electrode in a solution with pH 4,01 (at 25 ℃), gently stir and wait for the reading to stabilize (no changes for 5 seconds).
5. Press the "CAL" button for 5 seconds and release. Wait for the display to show 4.01 pH and stop flashing.
6. Clean the electrode in distilled water and dry (e.g. using a paper towel), then immerse the electrode in a solution with pH 9,18 (at 25 ℃), gently stir and wait for the reading to stabilize (no changes for 5 seconds).
7. Press the "CAL" button for 5 seconds and release. Wait for the display to show 9.18 pH and stop flashing.
8. Clean the electrode in distilled water and dry (e.g. using a paper towel), then place the meter back in the buffer solution to test the calibration. If it is incorrect, repeat the calibration.

1. Remove the protective cap. If crystals appear under it, this is not a cause for concern, this is normal with pH tester electrodes. The problem will disappear after rinsing the electrode with cleaning liquid/water.
2. Turn on the tester with the "ON/OFF" button and immerse the pH meter electrode in the test liquid. Gently mix until the displayed value stabilizes, then read the value from the display.
3. After the measurement, rinse the electrode with water and wipe with a cloth. Put on a protective cap

NOTE!

If the readings of the same liquid differ from each other, recalibrate the meter using the buffers included in the kit.

• Clean the electrode with distilled water each time before and after use
• Do not touch the sensor electrode, as the oil on the skin can damage the sensor and affect the readings.
• Do not immerse the meter in the solution above the immersion line to avoid damaging the circuits.
• After replacing the battery or opening the battery compartment, recalibration is necessary.
• Store the meter with a few drops of electrode storage fluid in the protective cap (e.g. GIB KCL or Growth Technology). Lack of this action may affect the correctness of readings and the life of the device.
• Large differences in readings can be due to the need for calibration, a dry electrode or weak batteries.
