PHS-25 Precise measurement laboratory pH meter
The Precise measurement PHS-25 pH meter is a precision digital display pH meter. It features a dual-row digital LCD display with blue backlighting, capable of simultaneously displaying pH and temperature values, or potential (mV) and temperature. This instrument is suitable for laboratory sampling and determination of pH and potential (mV) values of aqueous solutions in universities, research institutes, environmental monitoring facilities, and industrial and mining enterprises. With an ORP electrode, it can measure the ORP (oxidation-reduction potential) value of the solution. With an ion-selective electrode, it can measure the electrode potential value.
