Application Areas The BEC-200B model is widely used for continuous monitoring of conductivity values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. Performance Features Microcomputer-Based: Utilizes high-performance CPU chips, high-precision AD conversion technology, and SMT mounting technology to achieve multi-parameter measurement, temperature compensation, and automatic range switching, ensuring high accuracy and good repeatability. High Reliability: Touch keys, no switches, knobs, or potentiometers. Automatic Measurement Frequency Switching: Avoids electrode polarization and improves measurement accuracy. Phase-Sensitive Detection Design: Eliminates the influence of wires on measurements. 25°C Conversion: Temperature compensation with automatic measurement/manual input. Alarm Function: Isolated alarm signal output, with freely settable upper and lower alarm limits and alarm hysteresis cancellation. Industrial Control Watchdog: Ensures the instrument does not freeze. Network Function: Isolated current output and RS485 communication interface. Isolated Current Output: Upper and lower output limits for current corresponding to conductivity values can be freely set. Installation Methods: Flow-through, submerged, flange-mounted, or pipeline installation.
