DDSJ-318 Conductivity Meter



It can measure conductivity, resistivity. (TDS)total dissolved solids, salinity and temperature of the current solution.

It applies microprocessor-based technology and functions as automatic temperature compensation, auto-calibration, auto measuring range switch.

The user can calibrate thesensor constant or TDS conversion coefficient. Also, the instrument supports two-point calibration.

5.7 inch large touch screen, friendly Chinese language interface and easy use

It follows GLP practice

The stored data can be displayed by graphics and can be viewed, printed and deleted.

It allows the user to review current measuring date and the last calibration data.

It contains 3 kinds of measuring modes: Continuous measurement, timing measurement and balance measurement which can meet different measuring requirements.

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