DZB-718 portable multi-parameter meter

 Instrument functions:

u        Several parameters can be shown on the same screen. It can simultaneously measure pX/pH, mV, conductivity, TDS, salinity, resistivity, dissolved oxygen, saturation and temperature.

u        It provides many common ion modes such as H⁺、Ag⁺、Na⁺、K⁺、NH4⁺、Cl^-、F^-、NO₃^-、BF₄^-、CN^- ,Cu²⁺、Pb²⁺、Ca²⁺

u       It follows GLP practice and can store 2200 sets of measuring data.

u       It provides zero oxygen and full scale calibration.

u       It provides three measuring modes: continuous measuring, timing measuring and balance measuring mode.

u       It has USB ports. If matched with communication software, it can be connected with PC.

u        It is small size and low-energy designed. The protection level is IP65 for portable work and field measurement.
