ZJ-PHB-5 PH-Meter
ZJ-PHB-5 PH-Meter
Specification
◆ meter is a portable pH meter with LED double digits display, which display temperature and pH value simultaneously.
◆It is suitable for using in the laboratories of university, research institutes, environment monitoring, factories and mines inspection offices or field for measuring the pH value of the liquid and potential of the measuring electrode(mV).
◆It can also be used to measure electrode potential with various ion-selected electrode and measure oxy-reduction potential (ORP) value with ORP electrode.
