HI-710221-2 Conductivity and TDS Digital Panel Mount Controller information
Hanna's extended description
HI-710221-2 Conductivity and TDS Digital Panel Mount Controller
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
The Conductivity and TDS 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/RS485 output of 115V or 230V, and dual set point. The 710221-2 has a RS485 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.
TDS: 0.1ppm, 1ppm, 0.01 g/L (ppt), 0.1 g/L (ppt).
While the HI-700 series measures conductivity, the HI-710 models, complete with the same specifications, measure EC and TDS.

Mains powered - All mains operated equipment is compatible with UK AC voltage and frequency – 230V, 50Hz.

Water Resistant – Can withstand temporary exposure to water, but should not be submerged or washed under running water.
