Conductivity ORP Controller Model 2430P from Lakewood Instruments


Model 2430P Microprocessor-Based Conductivity and ORP Controllers

Conductivity,ORP,Controller,Model 2430P,Lakewood,InstrumentsLONWORKS* Technology is the latest in microprocessor capability that gives the user the highest level of application flexibility.

A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrade characterize this new technology.

The unit does not include plumbing or a sensor. For use with process-type conductivity sensors (order separately).

  • 4-electrode conductivity input includes fouling compensation and alarm.
  • Differential ORP sensor input with diagnostics indicate fouled reference or open PT band.
  • Input for flowswitch lockout.
  • Two water meter inputs, MTR1 and MTR2.
  • Conductivity Blowdown Relay options:
  • Bleed x gallons for every x gallons makeup
  • Bleed x minutes for every x gallons of makeup
  • Bleed by setpoint
  • Bleed by cycles of concentration with NCON/NCKT Option
  • Bleed by multi-setpoint selected with NCON/NCKT Option
  • Three user-selectable relay options (four additional with NRLY):
    • Feed by setpoint, direct or reverse;
    • Water meter actuated feed. MTR1, MTR2 or sum;
    • Feed after blowdown by percent of bleed time;
    • Feed by percentage of time;
    • Feed by schedule (-RTC Option);
    • General alarm contact.
    • Three security levels:
    • View only
    • Operator
    • Technician
