  PHB-5 type pH meter is a digital pH meter,it uses a blue backlight,double digital display LCD,it can show pH,temperature or potential (mV) value, This instrument applies to universities,research institutes,environmental monitoring,industrial and mining enterprises and other departments of the laboratory sample to measure the solution is pH value and potential (mV) value,coupled with ORP electrodes measure the solution ORP (oxidation-reduction potential) values.coupled with ion-selective electrode measures the value of the electrode of the electrode potential.

precision pH meter adopts 312 LED digital pH meter ,Its a perfect device for scientific research centers
