DZB-712 Portable Multi-parameter Meter

DZB-712 Portable Multi-parameter Meter

Instrument functions:

1. 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.

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

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

4. It provides zero oxygen and full scale calibration.

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

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

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