Performance Characteristics

Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology to complete multi parameter measurement, temperature compensation, and automatic range conversion, with high accuracy and good repeatability.
High reliability: touch sensitive buttons, no switch knob or potentiometer.
Automatic conversion of measurement frequency: avoids electrode polarization and improves measurement accuracy.
Phase sensitive detection design: eliminate the influence of wires on measurement.
25 ℃ conversion: temperature compensation automatic measurement/manual input.
Alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.
Industrial control watchdog: ensures that the instrument does not crash.
Network function: isolated current output and RS485 communication interface.
Isolation current output: The upper and lower limits of the conductivity value corresponding to the current can be set arbitrarily.
Adopt flow type, sinking type, flange type or pipeline installation.
