Conductivity Meter

DDK100 industrial on-line conductivity meter (hereinafter referred to as meter) is an on-line water quality monitor with microprocessor. The meter is equipped with conductivity electrodes of different types and constants for continuous monitoring and control of the conductivity and temperature of an aqueous solution. Widely used in power plants, petrochemical industry, metallurgy, paper industry, environmental protection water management, light industry, and other fields. Such as power plant cooling water, supply water, saturated water, condensate water and furnace water, ion exchange, reverse osmosis EDL, seawater distillation and other water production equipment raw water and water quality monitoring and control. The instrument is equipped with LCD display; Intelligent English menu operation; With current or voltage output, measuring range can be set freely, high and low over-limit alarm prompt and control switch of two groups of relays, hysteresis range can be adjusted; Automatic or manual temperature compensation;According to the needs of the user can provide [flow type] [pipe type] [sink type] [flange type] and other forms of installation process conductivity electrode.
