Hanna Conductivity Digital Controller with Four-ring Potentiometric Probe, Analog Output, 230V - HI700221-2

HI700221-2 Conductivity Digital Controller with Four-ring Potentiometric Probe, Analog Output, 230V by Hanna Instruments

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 our exclusive technology, they can be customized to best fit your application. Bright LED's show the current status even from a distance. 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.

With self-diagnostic features and extractable terminals, installation and maintenance are fast and simple. Password protection guarantees that the calibration and predetermined parameters cannot be altered unnecessarily. The controllers can operate with four-ring probe or 4-20 mA signal. They accept probes with or without a built-in Pt100 temperature sensor.

• Fully programmable microprocessor memory
• Dual set points
• mA & VDC recorder output
• Differential input for ground loop protection
• Automatic one or two point calibration
• Last calibration data
• Manual or Automatic Temperature Compensation
