HI 700 • HI 705 • HI 710 Hi-tech conductivity and TDS controllers

The HI 700 series of regulators offer state-of-the-art specifications for your process control. They can be configured for ON/OFF, Proportional, PI or PID control.

Thanks to Hanna exclusive technology, they can be customized to best fit your application. A menu driven display aids the user throughout the operations with running messages and clear prompts. All relevant parameters can be simply adjusted and will remain memorized until overwritten. Bright LED lights show the current status even from a distance. With self-diagnostic features and extractable terminals, installation and maintenance are rapid and simple.

Password protection guarantees that the calibration and predetermined parameters cannot be altered unnecessarily. The controllers can operate with 4-ring probe or 4-20 mA signal. They accept probes with or without a built-in Pt 100 temperature sensor. HI 710 monitors and controls both conductivity and TDS. If you only need conductivity or TDS, then order HI 700 or HI 705, respectively.
