FAQ
The ACS125 is available with K=0.1 or K=1.0 cm⁻¹. Selection depends on the expected conductivity range and the connected transmitter.
The specified process temperature range is 0–100°C, and the operating pressure range is 0–0.5 MPa.
The ACS125 normally requires a compatible conductivity transmitter or controller. PLC integration depends on the output or communication options of that instrument.
