Highest Quality – Low Cost – Superior Functionality

Part of a range of controllers, the CRIUS® is the big brother of the CRONOS® and offers more sensor connections, more functionality and more flexibility with a colour screen and optional built in 3G modem. The CRIUS® is an attractively priced, top of the range instrument controller. Optional communications packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP and others.

The CRIUS® is equipped with the capability to connect up to four sensors of any type with appropriate analogue outputs and relays. Four sensors not enough? Simply connect up to 4 CRIUS® together all using the same display and communications. Equipped with data-logging as standard and multiple PID loops as options, the CRIUS® is very able to control complex water treatment processes at a fraction of the cost of other controllers.

With all users having their own log on, and with three levels of instrument and remote access security, you can use the CRIUS® with all of its superior functionality with confidence. Chlorine analysers from Pi are used in many applications requiring the measurement and control of online residual chlorine levels in water. The HaloSense range is suitable for total or free residual chlorine monitoring or control applications in potable water, seawater, process water, swimming pool water, waste water, food washing, paper and pulp, etc.

The following are available in the HaloSense range;
•Online free and total chlorine 0.01-2 ppm, 0.01-5 ppm, 0.01-10 ppm, 0.01-20 ppm, 0.01-200 ppm (free chlorine only)

•Online residual chlorine in seawater analysers (free or total bromine) 0.01-2 ppm, 0.01-5 ppm, 0.01-10 ppm, 0.01-20 ppm

•Online zero chlorine (designed to measure the absence of free chlorine) 0.01-2 ppm for applications such as post activated carbon and pre-RO monitoring.

The HaloSense range of controllers/transmitters means that you get exactly what you need and nothing that you don’t. From a low cost no-frills chlorine dosing controller (CRONOS®) to a highly sophisticated colour display, remote access controller (CRIUS®) – and all with the same great sensors! Chlorine dosing control is now simpler and cheaper than ever! Both instruments can have multiple sensors and multiple sensor types, saving money on the requirement for one sensor and one transmitter per measurement.
