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^® 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.
