Highest Quality – Lowest Cost

Part of a range of controllers, the CRONOS® is the little brother of the CRIUS®. The CRONOS® is a high quality, low cost transmitter designed to give water treatment engineers everything that they need from a transmitter and nothing that they don’t. With no frills, costs can be kept to a minimum whilst optional communications packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, 4-20mA analogue outputs, and relays for alarms and control.

The CRONOS® has the capability to control up to two sensors of any type with appropriate analogue outputs and relays. Equipped with optional PID control, the CRONOS® is very able to control complex water treatment processes at a fraction of the cost of other controllers.

CRONOS Instrument Controller

CRONOS® plus Sensor equals…

  • Free Chlorine Analyser (HaloSense)
  • Total Chlorine Monitor (HaloSense)
  • Chlorine Dioxide Analyser (DioSense)
  • Ozone Monitor (OzoSense)
  • Dissolved Oxygen Meter (OxySense)
  • Suspended Solids Monitor (SoliSense®)
  • Turbidity Meter (TurbSense)
  • Streaming Current Monitor (StreamerSense)
  • pH Analyser (pHSense)
  • ORP Analyser (ORPSense)
  • Organics Monitor (UV254Sense)
  • Biofilm Monitor (BioSense)
  • Online Conductivity Monitor (ConductiSense)
  • Particle Counter (CounterSense)
  • Filter Monitor (FilterSense)
  • Fluoride Monitor (FluoriSense)
  • External inputs
  • Choose from Standard Configurations or ‘Build Your Own’

For each sensor the CRONOS® will prompt users through calibration procedures and will remind them when maintenance is due for each sensor type.


The CRONOS® is often used in applications where the remote access capability of the CRIUS® is not required. This doesn’t mean that a CRONOS® doesn’t have the capability of control! With full PID control, the CRONOS® is often used in application areas such as:

  • Water Treatment
  • Drinking Water
  • Waste Water
  • Pool and Spa Control
  • Industrial Water
  • Food and Drink
  • Paper and Pulp

The CRONOS® is a universal controller capable of outputting a PID control signal via an analogue (4-20mA) or a pulse width modulated relay (to control for example, an on/off pump). With the latest in communication options the CRONOS® is capable of running Profibus, Modbus or TCP/IP via Ethernet.

The ability to provide maintenance reminders is very attractive to larger users with multiple operators where it can be easy to miss scheduled maintenance.

The CRONOS® can also come in a multitude of languages making it suitable for use in any market.

Customers requiring additional functionality such as downloadable datalogging or remote access via the internet should consider the CRIUS® controller.
