Portable Multi-Parameter Analyzer (DZB-718)

Main Character:
* Display several parameter's measuring value at the same interface. Support to measure pX/pH, mV, conductivity, TDS, salinity, resistivity, DO, saturation, DO currency and temp. Value simultaneously.
* Provide several common ion modes randomly, such as H +, AG +, Na +, K +, NH4 +, Cl -, F -, NO3 -, BF4 -, CN -, Cu2 +, Pb2 + and Ca2 +. As long as user has relevant ion electrode, user could set up his own ion mode.
* Can view, print and delete measuring data.
* With USB interface, intelligent power management. If match with special communication software, it can be connected with PC.
* Three measuring modes: Continuous measuring mode, timed measuring mode and balance measuring mode.
* Support GLP regulation, can print and store 200 sets for each of pH, conductivity, TDS, salinity and DO. Allow to store 6 kinds of ion measuring value, including relevant pX value and ion concentration value 100 sets for each.
* Small in size, low power dissipation, IP65 protection class for easy moving and field measurement.
