Overview
DDG-2080D conductivity meter can choose between two to four channels, a multi channel conductivity meter is equivalent to two to four conductivity meter. Features 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 compensation automatically measured / manual input. Waterproof and dustproof design: The protection grade is IP65, and it is suitable for outdoor use. Technical Parameters 1.
