A pH meter
A pH meter determines acidity or alkalinity of a substance.
Using a calibrated pH-meter with correction for temperature and slope.
We can use a pH paper.
Purchase pH testing strips or use a pH meter.
These electrodes measure the pH value.
Using a pH-meter the measurement is more accurate and sure.

No, pH 2.77 is not the correct pH for 1 M HCl. The pH of 1 M HCl should be 0 (zero) because pH is the negative log the the H+ and for 1 M HCl the [H+] is 1 M, and the negative log of 1 is 0.
