Multi-Parameter Analyzer – CRONOS® and CRIUS®
Multi-sensor, multi-channel, multi-parameter analyzers can greatly reduce the cost per point of any measurements, including pH, residual chlorine, ORP, ozone, chlorine dioxide, dissolved oxygen and turbidity measurements, without risking the quality of those measurements.
Both the CRONOS® and CRIUS®4.0 controllers allow the connection of multiple sensors. For example, a CRIUS®4.0 may be made up of multi-sensors of the same variety, such as up to four chlorine sensors, or could be made up of a combination (multi-channel analyzer), such as a pH sensor, a chlorine sensor, and a turbidity sensor.
Whatever you need from your multi-channel analyzer, the CRONOS® and CRIUS®4.0 ranges will deliver.
CRONOS®
- Up to 2 sensor inputs
- Up to 2 outputs
- Up to 8 relays
- Up to 8 digital inputs
- Unlimited PID loops
CRIUS®4.0
- Up to 16 sensor inputs
- Up to 32 outputs
- Up to 32 relays
- Up to 32 digital inputs
- Unlimited PID loops
- Remote access (MQTT)
- Multiple digital comms options
CRONOS®
Any application where a high quality analyzer is required except in Hazardous Areas.
CRIUS®4.0
Almost any measurement or control application is suitable for the CRIUS®4.0 including; disinfection control in a variety of industries, coagulation control in the drinking water industry, aeration control in wastewater and many more.
Please choose the sensors of interest from the measurement drop down menu. Up to 16 of these sensors can be mixed and matched on a CRIUS®4.0.
