ATC function (Automatic Temperature Compensation) - temperature measurement and compensation indication of the tester in the range of 0-60°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.

1. Make 3 solutions with known pH using 250 ml of distilled water each and calibration buffers (4.01; 6.86; 9,18 pH included).
2. Dip the tester electrode into a solution with pH 6,86 (at 25℃) and wait for the reading to stabilize.
3. Press the "CAL" button (calibration) for 5 seconds and release. The display will display a flashing "CAL" then flashing 6,86 when the calibration for this point stops flashing has been completed.
4. Clean the electrode in distilled water and dry.
5. Repeat the procedure in sections 2 and 3 for solutions 4,01 and 9,18 pH.
6. Clean the electrode in distilled water and osusz.Umieść meter back in buffer solution to test 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

• 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.
• 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.

Re-calibration is required for:

• battery replacement,
• very frequent measurements,
• the display shows the message "ERR",
• long periods without measurements,
• the need for very accurate measurements.
