CRONOS®
Part of our controller range, the CRONOS® is the less capable, and therefore less expensive, cousin of the CRIUS®4.0.
The CRONOS® is a top-quality, low-cost transmitter designed to arm water treatment engineers with everything that they need from a transmitter, without any unnecessary hardware or firmware. With no frills, costs can be kept minimal, whilst optional communications packages allows for Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, 4-20mA analogue outputs, and relays for alarms and control.
As standard the CRONOS® comes with the same interface and firmware as the world-leading CRIUS®4.0, with all the same capability just reduced, so less I/O (up to 2 sensors) and a grayscale display.
The CRONOS® is capable of controlling up to two sensors of any type with relevant analogue outputs and relays. With optional PID control, the CRONOS® is quite capable of controlling complex water treatment processes, all at a fractional cost of other controllers.
- Up to 2 sensor inputs
- Up to 2 outputs
- Up to 8 relays
- Up to 8 digital inputs
- Unlimited PID loops
Any application where a high quality analyzer is required except in Hazardous Areas.
CRONOS® is a low cost, high functioning controller limited only on I/O and remote access capability (remote access is only available on CRIUS®4.0). Available options are;
- Color display
- Datalogging

FAQs
Which instrument controller from Pi should I choose?
What is the total number of sensors I can control with a CRONOS®?
What is the total number of outputs I can have with a CRONOS®?
Is datalogging available on the CRONOS®?
Is a color display available on the CRONOS®?
Not as standard, but this can be added for a fee. A color display is a standard feature of the CRIUS®4.0.
