Do you have to calibrate a pH meter?
For High-Accuracy measurements (≤ ±0.02pH), the meter should be calibrated before test every time; For general-accuracy Measurements (≥±0.1pH), once calibrated, the meter can be used for about a week or longer. …
What is ATC pH meter?
A: ATC stands for Automatic Temperature Compensation – this means the meter measures pH and temperature at the same time, then automatically calculates to correct for differences (e.g. if one sample is 20°C and another is 23°C).

How do I know if my pH meter is accurate?
A pH meter is considered accurate and in a good condition if the reading difference between the measurement and standard value is ≤ 0.30 pH.
Do you need distilled water to calibrate pH meter?
The electrodes of a pH meter will not give accurate values in pure water because distilled and deionised water do not have enough ions for the electrode to function accurately. … For calibration purposes, pH buffer solution is the best way to test your pH electrodes because it has a defined and accurate pH.
What is ATC and MTC?
The ATC is used to correct the temperature reading of the temperature sensor or probe connected to the meter while the MTC is used to enter the temperature reading of a separate temperature measuring device into the meter.
