PHS-3C laboratory acidity meter

●Overview

PHS-3C laboratory pH acidity meter is a liquid crystal display measuring instrument for measuring the pH value of the solution. It uses blue backlight double-row digital display liquid crystal, which can simultaneously display pH, temperature potential (mV), temperature value. The instrument is suitable for sampling measuring the pH value potential (mV) value of aqueous solutions in the laboratories of colleges, research institutes, environmental monitoring, industrial mining enterprises, the ORP electrode can be used to measure the ORP (oxidation-reduction potential) value of the solution. . Coupled with ion selective electrode, the electrode potential value of the electrode can be measured.
