Economical Portable MV And PH Meter

Model: PHB-5

TOP INSTRUMENT Economical Portable MV And PH Meter is a handheld device used for measuring the acidity or alkalinity of a solution.The portable design of the pH meter makes it easy to use in a variety of settings, and it is often battery-operated for added convenience.
  • PHB-5
  • TOP


  • It adopts blue backlight and double-row digital display liquid crystal, which can display pH value, temperature value or potential (mV) value at the same time.

  • It is suitable for laboratory sampling and determination of pH value and potential (mV) value of aqueous solution in universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments.

  • Equipped with an ORP electrode to measure the ORP (Oxidation-Reduction Potential) value of the solution.

  • Equipped with an ion-selective electrode, the electrode potential value of the electrode can be measured.
