The document is about the instruction manual of HI 720 Conductivity Process Controller with Inductive Probe. The product is a conductivity process controller that can improve product performance through online cleaning, temperature compensation, concentration curves, etc.
The Hanna Instruments HI 720 is a conductivity process controller that measures conductivity without electrical contact between electrodes and the process fluid. It utilizes inductive coupling via two toroidal transformers to determine the specific conductivity of the liquid passing through the sensor.
This manual provides comprehensive guidance on setting up, calibrating, and operating the device. Key features include auto-ranging, custom concentration curves, temperature compensation options, in-line cleaning capabilities, SMS messaging, and RS485 communication for data logging and control.
