KRYPTON® ONE | COMPACT
Expandable Water Quality Monitoring. Built for Advanced Process Control.
The KRYPTON® ONE | COMPACT 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 — 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 | COMPACT is its flexibility to easily adapt to your water process needs. In addition to the built-in I/O board with three expansion slots, this makes it the preferred choice for applications where measurement and control must work together in real time.
NEON ONE® | HUB relay expansion
Add relay-based process control through the NEON ONE | HUB for chemical dosing, pump control, alarm signaling, and other automation functions.
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 | COMPACT 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 | COMPACT 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.
