Description Instrument functions:

* 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.
* It provides many common ion modes such as H+, Ag+, Na+, K+, NH4+, Cl-, F-, NO3-, BF4-, CN-,Cu2+, Pb2+, Ca2+ (this is optional)
* It follows GLP practice and can store 2200 sets of measuring data.
* It provides zero oxygen and full scale calibration.
* It provides three measuring modes: continuous measuring, timing measuring and balance measuring mode.
* It has USB ports. If matched with communication software, it can be connected with PC.
* It is small size and low-energy designed. The protection level is IP65 for portable work and field measurement.
