TDS conductivity controller HI700 series

HI 700 and HI 710 high-performance microprocessor-based conductivity controllers, with two set points, all/nothing, P, PI or PID dosing, programmable analog output, four ranges in Conductivity or Total Dissolved Solids and two-point calibration, among other features, depending on the model. Microprocessor-based Conductivity Controllers with PID dosing, HI 700 - HI 710 HI 700 and HI 710 high-performance microprocessor-based panel conductivity controllers. Depending on the model, they have two set points, all/nothing, P, PI or PID dosing, programmable analog output, four ranges in Conductivity or Total Dissolved Solids as well as two-point calibration among other features. Configurable as Pl or PID proportional controller and fully programmable. Analog output. Calibration and programming operations are very simple with on-screen monitoring and are password protected from tampering. One model, the HI-700, measures conductivity only. HI-7639 4-ring potentiometric conductivity probe with platinum sensor and Pt100 sensor.
