AD28-1000 is a precision instrument specifically designed for detecting conductivity parameters in solutions, with simple operation and superior testing performance. 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.
main features

Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology to complete multi parameter measurement, temperature compensation, and range secondary meter electrode K=1
Automatic conversion, high accuracy, and good repeatability. 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 controlled watchdog: Ensure that the instrument does not crash.
Network function: isolated current output and RS485 communication interface. (Optional)

Isolation current output: The upper and lower limits of the conductivity value corresponding to the current can be set arbitrarily.

Electrodes with electrode constants of 0.01, 0.1, 1.0, or 10 can be selected based on the range of resistivity of the tested water sample, and can be installed in flow, submerged, flange, or pipeline configurations.
