KRYPTON® ONE | HUB
Expandable Water Quality Monitoring. Built for Advanced Process Control.
The KRYPTON® ONE | HUB is a fully integrated, expandable measurement and control system built on the NEON® ONE platform. Supporting up to six sensors across a comprehensive range of parameters, it delivers the flexibility and control capacity demanded by complex water treatment processes — arriving pre-mounted and pre-configured so your team can focus on operations, not installation.
Where the KRYPTON® ONE | COMPACT delivers streamlined monitoring, the HUB adds an integrated relay board for external process control — making it the right choice when your application requires not just measurement, but active, automated response.
Suitable components
More Than Measurement — Complete Process Control
The defining capability of the KRYPTON® ONE | HUB is its integrated relay board. In addition to the built-in I/O board with three expansion slots, the HUB includes dedicated relay integration for external control — enabling chemical dosing, pump switching, alarm triggering, and other automated process responses directly from the system. This makes it the preferred choice for applications where measurement and control must work together in real time.
Integrated relay board
Built-in relay integration for external process control — chemical dosing, pump switching, and alarm outputs.
Up to six sensors
Monitor multiple parameters simultaneously across disinfection, pH, ORP, conductivity, sulfite, and flow.
Modular I/O expansion
Three expansion slots on the integrated I/O board support flexible analog and digital output configurations.
Plug-and-play deployment
Pre-mounted and pre-configured on a panel — minimizing installation time and commissioning complexity.
SCADA/PLC ready
Seamless integration with external control systems via mA outputs or Modbus TCP over Ethernet.
P/PI/PID control
On/off and full PID control modes available for every measurement parameter except temperature.

Typical Applications
KRYPTON® ONE | HUB is designed for applications where multi-parameter monitoring must be paired with active process control:
- Municipal water treatment and disinfection systems requiring automated chemical dosing control
- Food and beverage processing where chemical levels must be maintained within tight tolerances
- Industrial water treatment — cooling towers, boiler feedwater, and process water systems
- Pool and spa facilities requiring integrated disinfection measurement and chemical dosing
Software Options
KRYPTON® ONE | HUB supports the full NEON® ONE software suite for advanced automation, validation, and integration:
NEON® ONE ASR® — Automatic Sensor Cleaning
Automated cleaning for up to four ZIRKON® ONE DIS sensors. Reduces maintenance demands and extends sensor life in fouling-prone water conditions.
NEON® ONE Validation
Validates chlorine measurement in chlorine-free water — critical for reverse osmosis pre-treatment and emergency chlorination applications.
NEON® ONE Modbus TCP
Real-time data exchange with PLCs, SCADA, and building automation systems over Ethernet for seamless integration into existing control infrastructure.
NEON® ONE Toolkit
Define custom automation events, control digital I/O and relays, and build schedule-based process logic within the NEON® ONE platform.
