What is ATC probe in pH meter?
What is ATC probe in 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). pH meters that do not have ATC are markedly less accurate.
What is pH meter?
pH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode. When the two electrodes are immersed in a solution, they act as a battery.
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.
Why does a pH meter have an ATC?
pH ATC improves accuracy and keeps the electrode in calibration regardless of temperature. During calibration, ATC reads the true temperature of the buffer and assigns the exact correct value.

Why are pH meters better than indicators?
In summary, pH meters are usually much more precise and accurate than test strips. When a test strip is used, it changes color and is compared with a color chart. A problem with this is that different people see colors differently and may tend to interpret the color comparison in different ways.
What is refillable pH electrode?
Refillable glass pH electrodes contain liquid electrolyte solution, which serves to close the electrical circuit in a pH electrode. Contact is made via a semipermeable junction, which permits a consistent outflow of liquid electrolyte.
What is the method to calibrate the pH meter?
How to calibrate a pH meter
- Examine the pH electrode. First, check the pH electrode for contamination or damage.
- Flush the pH sensor. Next, flush your sensor with distilled water.
- Immerse the pH electrode.
- Calibrate the pH meter.
- Rinse the pH sensor and repeat.
What is MTC in pH meter?
Manual Temperature Compensation (MTC) – MTC provides the ability to demonstrate the effect of temperature on pH measurement. It is simple to use and allows for different temperature corrections based on the sample being tested. Analog Output- Allows a recording device to be connected to the meter.
How does pH meter ATC work?
pH ATC improves accuracy and keeps the electrode in calibration regardless of temperature. During calibration, ATC reads the true temperature of the buffer and assigns the exact correct value. During testing, ATC reads the true temperature of the sample and adjusts the slope to remain in collaboration.
