PHS-2C precision pH meterPerformance characteristics:

The PHS-2C pH meter is a digital display pH meter that uses blue backlight and dual row digital display LCD to simultaneously display pH, temperature value, or potential (mV) and temperature value. This instrument is suitable for sampling and measuring the pH value and potential (mV) value of aqueous solutions in laboratories of colleges, research institutes, environmental monitoring, industrial and mining enterprises, and other departments. It can also measure the ORP (oxidation-reduction potential) value of solutions when equipped with ORP electrodes. Paired with an ion selective electrode, the electrode potential value of the electrode can be measured.
