DZS-708 Multi-parameter Water Quality Meter

DZS-708 Multi-parameter Water Quality Meter

Instrument functions:

1. It has 5.7 inch large touch screen and English operation system for easy use.

2. It can measure pH, pX, ORP, ion concentration, conductivity, resistivity, TDS, salinity, dissolved oxygen, saturation and temperature at the same time.

3. It provide many ion modes such as H+、Ag+、Na+、K+、NH4+、Cl-、F-、NO3-、BF4-、CN- Cu2+、Pb2+、Ca2+  The users can define ion modes by themselves if choosing corresponding ion sensors.

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

5. Measuring data can be viewed, printed and deleted. The user can view current measuring data and the last calibration data.

6. It provides zero oxygen and full scale calibration,.

7. It has RS-232 and USB ports. If matched with specific data collecting software, it can be connected with PC.

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