High Quality­Low Cost

Part of a range of controllers, the CRONOS® is the little brotherof the CRIUS®. The CRONOS® is a high quality, low costtransmitter designed to give water treatment engineerseverything that they need from a transmitter and nothing thatthey don't.

Superior Communications

With no frills, costs can be kept to a minimum whilst optionalcomms packages allow Profibus, Modbus ASCII, Modbus RTU,Modbus TCP, 4­20mA analogue outputs, and relays for alarmsand control.

PID Control Options

CRONOS® has the capability to control up to two sensors of anytype with appropriate analogue outputs and relays. Equippedwith optional PID control CRONOS® is very able to controlcomplex water treatment processes at a fraction of the cost ofother controllers.

Proactive Sensor Maintenance

For each sensor the CRONOS® will prompt users throughcalibration procedures and will remind them when maintenanceis due for each sensor type.

Customers requiring additional functionality such as a colourdisplay, downloadable data logs, or remote access via theinternet should consider a CRIUS® controller.
