Three verified model configurations
Analog sensors · PEC-500 / 500E / 500F
Analog Conductivity Sensor Series
Three analog sensor constructions cover general water treatment and low-to-medium conductivity ranges with different cell constants, materials and mounting threads.
PEC-500 / 500E / 500FK=0.01–1.0≤0.6 MPa
Structured from the supplied technical files
Only values confirmed in the current records are published. Products without a commercial model remain configured products; final range, cell constant, material, interface and accessories are controlled by the project datasheet.
