Pengukur pH adalah instrumen ilmiah yang mengukur aktivitas ion hidrogen dalam larutan berbasis air, yang menunjukkan keasaman atau kebasaannya yang dinyatakan sebagai pH. Pengukur pH mengukur perbedaan potensial listrik antara elektroda pH dan elektroda referensi, sehingga pengukur pH terkadang disebut sebagai "pengukur pH potensiometri". Perbedaan potensial listrik berkaitan dengan keasaman atau pH larutan. Pengukur pH digunakan dalam banyak aplikasi mulai dari eksperimen laboratorium hingga kontrol kualitas
