PHB-5 portable PH meter Introduction
The PHB-5 portable PH meter is a digital display pH meter that uses a blue backlit, dual-row digital display LCD that simultaneously displays pH, temperature, or potential (mV) values. The instrument is suitable for the measurement of the pH value and potential (mV) value of the aqueous solution in the laboratory of universities, research institutes, environmental monitoring, industrial and mining enterprises, etc., and the ORP electrode can measure the ORP (oxidation-reduction potential) value of the solution. The electrode potential value of the electrode can be measured by an ion selective electrode. Technical Parameters
