DDG-2080D (Multi-channel Industrial Online) Conductivity meter can choose between two to four channels, a multi-channel conductivity meter is equivalent to two to four conductivity meter.
Characteristics:
Customers can arbitrarily choose Dual channel conductivity meter, three channel conductivity meter or four channel conductivity meter. All the channels are mutually independent, none interfering, and most can be connected with four electrodes at the same time.

English liquid crystal display, English menu operation.

Computer-based: It adopts the high-performance CPU chips, high-precision AD conversion technology and

SMT technology to complete the multi-parameter measurement, temperature compensation and automatic rang

switching, with high precision and good repeatability.

Phase-sensitive detection: With such detection, the impact of wires on conductivity measurement can be

eliminated.

25℃ conversion:Temperature compensationautamatically measured/ manual input.

Isolation of 4 ~ 20 mA current output, discretionary setting of upper and lower thresholds for the

current corresponding to conductivity value output
