HI-700221-2 Conductivity Digital Panel Mount Controller
HI-700221-2
The HI-700 and HI-710 series of controllers, especially designed for EC or TDS control, offer state of the art specifications for your process control. Panel-mounted, they can be configured for ON/OFF, proportional, PI or PID control.
The Conductivity Digital Controller is panel-mounted and provides accurate measurements thanks to the four-ring EC probe and automatic temperature compensation (ATC Feature).
Users can choose from models featuring on/off or PID control, analogue output of 115V or 230V, and dual set point. The 700221-2 has an analogue output of 230V.
The controller measures 144 x 144mm x 170mm, and weighs 1.6kg (3.5lb). Panel cut out: 140mm x 140mm.
EC Range 0.0 to 199.9 µS/cm, 0 to 1999 µS/cm; 0.00 to 19.99 mS/cm; 0.0 to 199.9mS/cm.
While the HI-700 series measures conductivity, the HI-710 models, complete with the same , measure EC and TDS.
Thanks to our exclusive technology here at Hanna, this controller can be customised to best fit your application.
Bright LEDs show the current status - even for 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 memorised until overwritten.
A password protection feature keeps the controllers safe from tampering.
- CAL Check™ – Alerts users of calibration status
- ATC – Automatic temperature compensation
- 2 point calibration
- Backlight – Backlit, LCD Display
