Benchtop pH/mV Meter

Model: PHS-3D

TOP INSTRUMENT Benchtop pH/mV Meter is a digital display pH meter, which uses white backlight, double-row digital display LCD, which can display pH, temperature value or potential (mV), temperature value at the same time. It is suitable for laboratories in colleges and universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments to take samples to measure the pH value and potential (mV) value of aqueous solution, and can measure the ORP (oxidation-reduction potential) value of the solution with an ORP electrode.
