Instrument functions:
uSeveral parameters can be shown on the same screen. It can simultaneously measure pX/pH, mV, conductivity, TDS, salinity, resistivity, dissolved oxygen, saturation and temperature.
uIt provides many common ion modes such as H+、Ag+、Na+、K+、NH4+、Cl-、F-、NO3-、BF4-、CN-,Cu2+、Pb2+、Ca2+
uIt follows GLP practice and can store and print 2200 sets of measuring data.
uIt provides zero oxygen and full scale calibration.
uIt provides three measuring modes: continuous measuring, timing measuring and balance measuring mode.
uIt has USB ports. If matched with communication software, it can be connected with PC.
uIt is small size and low-energy designed. The protection level is IP65 for portable work and field measurement.
