SUP-EC8.0 Conductivity Meter, Conductivity Controller for EC, TDS, and ER Measurement
Introduction
The SUP-EC8.0 Industrial Online Conductivity Meter is a high-level intelligent chemical analyzer providing continuous, multi-parameter monitoring for demanding industrial processes. It integrates the crucial measurements of Conductivity (EC), Total Dissolved Solids (TDS), Resistivity (ER), and temperature into one robust unit. This controller offers exceptional versatility with an ultra-wide measurement span, ranging from 0.00 µS/cm up to 2000 mS/cm, and maintains ±1%FS accuracy.
Designed for operational resilience, the meter features precise temperature compensation utilizing NTC30K or PT1000 sensors across an extended temperature range (-10°C – 130°C. Its control and communication capabilities are fully optimized for automation, providing three essential outputs: standard 4-20mA analog current, Relay outputs for direct control actions, and digital RS485 utilizing the Modbus-RTU protocol. Powered universally by 90 to 260 VAC, the SUP-EC8.0 is an indispensable, reliable solution for water quality management in sectors like power generation, pharmaceuticals, and environmental processing.
