DZS-707 Multi-parameter Water Quality Analyzer |  NOTEBook is Option | | | Characteristic: | | * It can test simultaneously the temperature, pH (electrode potential), conductivity (TDS, salinity) and dissolved oxygen (saturation) for the same sample. | | * Virtual operation system and modularization electronic unit transformer can transfer the signal of each sensor to computer for further settlement. The software of the computer has all operation and analysis function. With small size, lower price. | | * The operation software based on Windows has data settlement function which can record down manually or automatically the measuring datum, display these data through diagram of curves or chart and save as Access pattern. The data can also be transferred to Word or Excel. | | * The software has the function of copying the diagram of curves. Copy the diagram of curves to clip board so that the other software can paste and use it. | | * Connecting the transformer to computer through RS-232 or Ethernet, meter can be operated in long-range. | | * Software supports system connection. By connecting meter with system server through Ethernet, the testing information such as sample serial number, testing person, testing data, testing date and time etc. can be sent to the system server for comprehensive settlement. | | | | Spec: |
