Inductive Conductivity Meter DDG-2080C

High reliability

Parts integrate in a circuit board without any complex function switch, regulation knot or potentiometer.

Strong resistance to interference

Current output adopts photoelectricity coupling and isolation technology which holds strong resistance to interference and realizes long distance transmission as well as good electromagnetic compatibility.

Design with waterproof and dust-proof

The degree of protection is IP65 which is suitable for outdoor operation.

25℃ translation

It provide 25℃ base temperature translation of the measured conductivity, so the conductivity value at 25℃ can be directly displayed. This is particularly suitable for measurement of water quality in power plants.

Range automatic change

Realization of range automatic change within the range of the electrode covered.

RS485 communication interface

Easily connects to the computer for monitor and communication.

Phrase-sensitive detection

Remove the affect on the hydrochloric acid concentration measurement by the wire.

Automatic change the measurement frequency

avoid the polarization of electrode and improve the measure precision.

Simple menu structure and text-type man-machine interaction

Compared with traditional instruments, is provided with many new functions. However, with sorted menu structure and the operation manner similar to PC, it can be conveniently and simply operated. Users need not remember the operation steps and sequences, and can operate it even without a user manual, just following the prompts on the screen.

Multi-parameter display in the same screen

It displays several parameters in the same screen, including conductivity, output current, temperature, time and status. The main display area displays conductivity in 10×10mm, very striking and readable even far away; The 6 auxiliary display areas display in 5×5mm the output current, temperature, status, week, date and time, designed to meet different habits of users and provide time base for the instrument.

Conductivity measurement range

0.01～20μS/cm (with 0.01 electrode), actually up to 100.0μS/cm;

0.1～200μS/cm (with 0.1 electrode), actually up to 1000.0μS/cm;

1.0～2000μS/cm (with 1.0 electrode), actually up to 10000.0μS/cm;

10～20000μS/cm (with 10.0 electrode), actually up to 10000.0μS/cm;

30～600.0mS/cm (with 30.0 electrode).
